1 MB response size limit with outlook web add-ins - outlook

I'm using makeEwsRequestAsync to get the full MIME content of the email. But it looks like response size is capped at 1 MB, per the error message in the response:
"ErrorMessage":"Response exceeds 1 MB size limit. Please modify your EWS request.”
<GetItem xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">
<ItemShape>
<t:BaseShape>IdOnly</t:BaseShape>
<t:AdditionalProperties>
<t:FieldURI FieldURI="item:MimeContent"/>
</t:AdditionalProperties>
</ItemShape>
<ItemIds><t:ItemId Id="' + itemId + '"/></ItemIds>
</GetItem>
I need to get MIME content of messages which may exceed 1 MB, and also POST such content to our server. Is there any way to increase this limit in the request, or configure this on the Exchange side?

It is not possible to make EWS requests to the client side that exceed 1 MB, however you can give your server the information that it needs to make the request itself.
You first need to call Office.context.mailbox.getCallbackTokenAsync which will give you a token you can use to make EWS requests from your server.
Then you will need to get the item ID which is available through Office.context.mailbox.item.itemId.
Finally, you need the url to make the request to, which is Office.context.mailbox.ewsUrl
With these 3 pieces of information, your server can make the SOAP call to EWS from your backend, and bypass the 1 MB limit imposed on the client. At this point, you can pass whatever information needed back to your client.

Max payload size for post request and Get response for SpringBoot Rest

Is there any max size for send post payload ?
Actually, I have a service which send a json payload to another micro-service, In side of JSON payload, there is a filed which hold encoded String (basically i have converted file into encoded String and set it into that payload field value).
File size is not fixed, So i am curious about it, is there any max size support for Post json payload ?
I know spring-boot have following properties for set max size for file upload.
spring.http.multipart.max-file-size
spring.http.multipart.max-request-size
But as i mentioned i am not upload file, i am convert file into encoded string and send this string with json payload.
So how can i set the max size support for post request.
Also In another scenario I am hitting a Get request to micro-service and then this micro service return a large payload,is there any limitation of receive payload size?
It depends, not only in spring configuration as you've pointed, but also in server configuration.
Most servers have a post request loadout limit. For example in tomcat you can configure it with the "maxPostSize" property. Quoting from the documentation:
The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing.
The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Firefox ignoring response header content-range and playing only the sample sent

I have built an audio stream for mp3 files, and each time client hits the audio it receives something like this:
But what it does is just plays 1 minute sample instead of 120 minute
What am I doing wrong here?
Not 100% sure because you didn't provide code or an example stream to test, but your handling of HTTP range requests is broken.
In your example request, the client sends Range: bytes=0-, and your server responds with a 1MiB response:
Content-Length: 1048576 (aka. 1 MiB)
Content-Range: 0-1048575/...
This is wrong, the client did not request this! It did request bytes=0-, meaning all data from position 0 to the end of the entire stream (See the http 1.1 RFC), i.e. a response equal to one without any Range. (IIRC, Firefox still sends the Range: bytes=0- to detect if the Server handles ranges in the first place).
This, combined with the Content-Length, leads the client (Firefox) to think the whole resource is just 1MiB in size, instead of the real size. I'd imagine the first 1 MiB of your test stream comes out as 1:06 of audio.
PS: The Content-Duration header (aka. RFC 3803) is something browsers don't usually implement at all and just ignore.
Just an idea. Did you tried some of the http 3xx header like:
'308 Resume Incomplete' or '503 Service Temporarily Unavailable' plus 'retry-after:2' or '413 Request Entity Too Large' plus 'retry-after:2'

Strategies in reducing network delay from 500 milliseconds to 60-100 milliseconds

I am building an autocomplete functionality and realized the amount of time taken between the client and server is too high (in the range of 450-700ms)
My first stop was to check if this is result of server delay.
But as you can see these Nginx logs are almost always 0.001 milliseconds (request time is the last column). It’s hardly a cause of concern.
So it became very evident that I am losing time between the server and the client. My benchmarks are Google Instant's response times. Which almost often is in the range of 30-40 milliseconds. Magnitudes lower.
Although it’s easy to say that Google's has massive infrastructural capabilities to deliver at this speed, I wanted to push myself to learn if this is possible for someone who is not that level. If not 60 milliseconds, I want to shave off 100-150 milliseconds.
Here are some of the strategies I’ve managed to learn.
Enable httpd slowstart and initcwnd
Ensure SPDY if you are on https
Ensure results are http compressed
Etc.
What are the other things I can do here?
e.g
Does have a persistent connection help?
Should I reduce the response size dramatically?

I may well be wrong, but personally I smell a rat. Your times aren't justified by your setup; I believe that your requests ought to run much faster.
If at all possible, generate a short query using curl and intercept it with tcpdump on both the client and the server.
It could be a bandwidth/concurrency problem on the hosting. Check out its diagnostic panel, or try estimating the traffic.
You can try and save a response query into a static file, then requesting that file (taking care as not to trigger the local browser cache...), to see whether the problem might be in processing the data (either server or client side).
Does this slowness affect every request, or only the autocomplete ones? If the latter, and no matter what nginx says, it might be some inefficiency/delay in recovering or formatting the autocompletion data for output.
Also, you can try and serve a static response bypassing nginx altogether, in case this is an issue with nginx (and for that matter: have you checked out nginx' error log?).
One approach I didn't see you mention is to use SSL sessions: you can add the following into your nginx conf to make sure that an SSL handshake (very expensive process) does not happen with every connection request:
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
See "HTTPS server optimizations" here:
http://nginx.org/en/docs/http/configuring_https_servers.html
I would recommend using New Relic if you aren't already. It is possible that the server-side code you have could be the issue. If you think that might be the issue, there are quite a few free code profiling tools.
You may want to consider an option to preload autocomplete options in the background while the page is rendered and then save a trie or whatever structure you use on the client in the local storage. When the user starts typing in the autocomplete field you would not need to send any requests to the server but instead query local storage.
Web SQL Database and IndexedDB introduce databases to the clientside.
Instead of the common pattern of posting data to the server via
XMLHttpRequest or form submission, you can leverage these clientside
databases. Decreasing HTTP requests is a primary target of all
performance engineers, so using these as a datastore can save many
trips via XHR or form posts back to the server. localStorage and
sessionStorage could be used in some cases, like capturing form
submission progress, and have seen to be noticeably faster than the
client-side database APIs.
For example, if you have a data grid component or an inbox with
hundreds of messages, storing the data locally in a database will save
you HTTP roundtrips when the user wishes to search, filter, or sort. A
list of friends or a text input autocomplete could be filtered on each
keystroke, making for a much more responsive user experience.

Yammer JSON Feed returning only 20 messages

I am trying to get all the messages from a particular group. I am getting the json feed back. The only problem is, its returning only 20 messages. Is this set as default or something. Is there any way by by which while doing the request, I can specify whether I want all the messages, by default just 20 or even messages posted between the start and the end date?
My RestApi call is:
https://www.yammer.com/api/v1/messages/in_group/[id].json
From Yammer Developer Documentation
<
Autocomplete: 10 requests in 10 seconds.
Messages: 10 requests in 30 seconds.
Notifications: 10 requests in 30 seconds.
All Other Resources: 10 requests in 10 seconds.
These limits are independent e.g. in the same 30 seconds period, you could make 10 message calls and 10 notification calls. The specific rate limits are subject to change but following the guidelines below will ensure that your app is not blocked.>>
I have tried using limit as the parameter to change the number of message more than 20. But it doesnt seem to be working?
Is this problem because of Rate Limit. If not, what's the problem?
Official documentation from Yammers Developer documentation
Messages - Viewing Messages
Endpoints:
1) All public messages in the user’s (whose access token is being used to make the API call henceforth referred to as current user) Yammer network. Corresponds to “All” conversations in the Yammer web interface.
GET https://www.yammer.com/api/v1/messages.json
2) The user’s feed, based on the selection they have made between “Following” and “Top” conversations.
GET https://www.yammer.com/api/v1/messages/my_feed.json
3) The algorithmic feed for the user that corresponds to “Top” conversations, which is what the vast majority of users will see in the Yammer web interface.
GET https://www.yammer.com/api/v1/messages/algo.json
4) The “Following” feed which is conversations involving people, groups and topics that the user is following.
GET https://www.yammer.com/api/v1/messages/following.json
5) All messages sent by the user. Alias for /api/v1/messages/from_user/logged-in_user_id.format.
GET https://www.yammer.com/api/v1/messages/sent.json
6) Private messages received by the user.
GET https://www.yammer.com/api/v1/messages/private.json
7) All messages received by the user.
GET https://www.yammer.com/api/v1/messages/received.json
Parameters:
The messages API endpoints return a similar structure and support the following query parameters:
older_than - Returns messages older than the message ID specified as a numeric string. This is useful for paginating messages. For example, if you’re currently viewing 20 messages and the oldest is number 2912, you could append “?older_than=2912″ to your request to get the 20 messages prior to those you’re seeing.
newer_than - Returns messages newer than the message ID specified as a numeric string. This should be used when polling for new messages. If you’re looking at messages, and the most recent message returned is 3516, you can make a request with the parameter “?newer_than=3516″ to ensure that you do not get duplicate copies of messages already on your page.
threaded=[true | extended] - threaded=true will only return the first message in each thread. This parameter is intended for apps which display message threads collapsed. threaded=extended will return the thread starter messages in order of most recently active as well as the two most recent messages, as they are viewed in the default view on the Yammer web interface.
limit - Return only the specified number of messages. Works for threaded=true and threaded=extended.
Noted the limit parameter that you can set on your GET request - so based on this documentation if it is correct (I'm not a Yammer Developer but I do use it) you should be able to do
https://www.yammer.com/api/v1/messages.json?limit=50
That is in theory but reading through the documentation there is a section on Search that has
page - Only 20 results of each type will be returned for each page, but a total count is returned with each query. page=1 (the default) will return items 1-20, page=2 will return items 21-30, etc.
Which says to me they are limited to 20 results returned.
UPDATE
After testing this with https://www.yammer.com/api/v1/messages.json?limit=50 and it not returning 50 messages but doing https://www.yammer.com/api/v1/messages.json?limit=5 will return only 5 messages I would say that Yammer restrict the number of messages to 20 Also after reading through the documents a bit more I read
For example, if you’re currently viewing 20 messages and the oldest is number 2912, you could append “?older_than=2912″ to your request to get the 20 messages prior to those you’re seeing"
This says to me that they will only return a max of 20. So I think you are stuck with 20 messages at a time.
Hope this helps.
You need to use Parameters:

limit - Return only the specified number of messages. Works for threaded=true and threaded=extended.
Example : GET https://www.yammer.com/api/v1/messages.json?older_than=2912
while older can be ID of message number 20 and so on you can get 20 by 20
I solved by requesting subsequent pages in a recursive manner.
You can simply increase the page parameter until the response is empty, or update the older_than parameter until the property meta.older_available is false.

AppFabric QuotaExceededException

When trying to insert a large item into the AppFabric cache I get an error
Microsoft.ApplicationServer.Caching.DataCacheException:ErrorCode<ERRCA0016>:SubStatus<ES0001>:The connection was terminated, possibly due to server or network problems or serialized Object size is greater than MaxBufferSize on server.

The problem is I can find very little documentation on this issue.
I can see various links discussing the issue all pointing to sites that no longer exist.
e.g.
http://www.biztalkgurus.com/appfabric/b/appfabric-syn/archive/2011/04/19/understanding-the-windows-azure-appfabric-service-bus-quotaexceededexception.aspx
I've also found the following which discusses setting the MaxReceivedMessageSize property.
http://msdn.microsoft.com/en-us/library/ee677250(v=azure.10).aspx
However on my install of AppFabric 1.1 on Windows server I don't have the cmdlet Set-ASAppServiceEndpoint and cannot find where to locate it.
Error not in AppFabric. The service need more size to transmit messsage to other endpoint. You remember this configuration must be the same at both endpoints.
