I'm using script which is uploading files to server via flash component. Sometimes, very rarely, when trying to upload images via Firefox I get following error: IO error #2038. Searching on the net I could find reason why is it really happening to me. But I found solution for my case:
I open IE6, do the same thing there (photos are always uploaded without problem) and the when I try again in Firefox problem disappears. If someone had similar problems maybe this could help or maybe this hint could help to someone discovering cause of the problem :)
I just had this error also using ASP.Net MVC and I discovered I just had my handler namespace wrong/missspellled in the web config section where the handlers go. HTH...
After far more time than I'd like to admit, here is the solution. Change the following variables in your php.ini to be large enough to handle your largest file:
; Maximum size of POST data that PHP will accept.
post_max_size = 32M
; Maximum allowed size for uploaded files.
upload_max_filesize = 32M
; Whether to allow HTTP file uploads. (this is on by default)
file_uploads = On
Since files are sent as POST data, both the first variables need to be set. Otherwise, there will be an error, but you won't see what the error is, except IO error #2038.
If you didn't add quote around the option names, try doing that. Sometimes in IE, quoting the option names fixes the issue. It would help if you posted some example code though.
Also make sure that the path to the server being used by the upload component is correct. If the path is a relative path, try to fully qualify it. IE can do some "magic" with relative paths that the other browsers cannot do, and sometimes trying the code from one browser to the other can tweak things.
Also, could be permissions...and having IE go there first could manipulate the permissions in a way that the other browser(s) then work "correctly".
I solved the problem.
In my office I use a proxy and I must change the settings to No Proxy.
Or if you do not use proxy, try to change in php.ini:
Hostname:Port localhost:0
to:
Hostname:Port localhost:80

I have an mp3 file in an S3 bucket. I am fetching this file via ajax GET request for html5 audio playback. Intermittently, the get request will fail to download the file and thus the track will not play. The request returns "206 partial content." Oddly, it will work several times before failing and then continuing to fail.
If I disable caching in my browser (chrome), the file will download and play appropriately.
Have I configured s3 incorrectly? How can I get this mp3 file to download and play consistently?
specific file is located here: https://s3.amazonaws.com/1m40s_dev/assets/music/walden.mp3
thanks!
I've found this often relates to the MIME type set on the S3 hosted file.
Setting the correct MIME type seems to fix things.
On a side note, I struggled with a single binary file always breaking in IE. Its MIME type was application/octet-stream. I changed the MIME to binary/octet-stream and that seemed to fix downloads from IE. Not sure why.
use amazon cloudfront solve the problem
I solved this by appending a timestamp to the end of the mp3 url on page load. This forced a new download of the content each time and eliminated the caching error.
This feels more like a work around than a fix. I still don't know the root cause of the issue but if you find yourself having a similar problem and just need to move on, add a timestamp or random number as a param at the end of the url
.../assets/music/walden.mp3?[timestamp]
One other workaround I've found is, if you're using rails, turning off turbolinks makes this go away on chrome. I'll add more to my answer as I discover more.
I'm using ABCPdf to convert HTML to a PDF. I'm using the method:
AddImageUrl()
This works fine in Dev and UAT, but on Production I continuously get the message:
Unable to render HTML. Unable to load
page
Anyone see this before? Need more info?

I guess you are tying to do URL->pdf generation. It is difficult to directly to do URL->pdf conversion. We ended up URL-Save HTML in local folder ->read HTML and convert to PDF-> delete HTML file from folder - tricky approach but it works. The only flaw is that you need to give read/write permission on a folder on server. Its still better than decreasing security settings.
have you take a look at this http://www.itjungles.com/dotnet/abc2pdf-unable-to-render-html
The default timeout for abcpdf is 15 seconds. If the page is taking longer than 15 seconds, you will get this exception.
Add the line below just after object creation of the document to resolve the issue.
theDoc.XHtmlOptions.Timeout = 10000000;
I found by working backwards (removing elements) from a target html page that omitting the tag (of all things) created this error. also, calling localhost in the target url generated this error.
I have no idea what caused this error, but I stopped the scheduled task that was running, then restarted it and it's worked fnie ever since.
i got this error
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header
information - headers already sent by
(output started at
/home/rapcomdk/public_html/system/language/danish/imglib_lang.php:1)
Filename: helpers/url_helper.php Line
Number: 541
i dont know what the problem is
here is my controller:

and here is my model file:

hope some one can help me out
Check and make sure in system/language/danish/imglib_lang.php that you have no whitespace before the <?php tag and make sure you do not have a closing ?> php tag in the file.
In addition to jondavidjohn's answer, if you're using Unicode encoding for the files, make sure there's not a byte order mark starting off the file. On some platforms, this can wreak havoc on PHP processing.
Make sure there are no errors in codeigniter, sometimes the errors can be covered by other errors, such as one error lead to another.
The problem is in system/language/danish/imglib_lang.php, which must have some character before the <?php part by the time it is parsed on the server. What's happening is that helpers\url_helper.php is trying to redirect (using this code;)
case 'refresh' : header("Refresh:0;url=".$uri);
But is failing because imglib_lang.php, line 1 has already sent some non-header text to the response. Since headers come first, it's giving you the warning.
I wonder at it working locally but not on the deployment server. It may be that the file is not being transferred cleanly, or that the servers use different versions of PHP with different handlings of character sets.
Several checks;
Be absolutely sure there is no BOM at the front of system/language/danish/imglib_lang.php. Let us know why you are certain. If you've edited the file in Notepad on windows, for instance, it'll have gained the Byte Order Mark. It can be very hard to tell since some tools 'swallow' the mark. Also make sure there's no plain whitespace.
When you save imglib_lang.php, make sure you save it in ASCII.
Compare local and remote versions of PHP. If there are differences, update your local copy to the same as the servers, and retest.
Check that the file is being transferred perfectly. If you are putting the file up using FTP, then FTP may be modifying it as it transfers it. FTP has two modes - an ASCII mode and a BINARY mode. If the files are being transferred as ASCII, then there may be some rewriting of the file going on. Try making sure imglib_lang.php is being transferred as BINARY to make sure the exact file is being uploaded.
If you think that you have everything configured correctly, maybe your library (or specifically, imglib_lang.php) is simply producing PHP warnings or notices. If you can get a hold of your logs from your host, it would be helpful.
Otherwise, you can try to turn off PHP's error reporting:
error_reporting(0);
(you can place that line in your index.php)
I want to change the settings of firefox so as to allow it to make cross domain ajax calls. Since due to the security feature of the firefox it doen't allow ajax calls to be made. I know if it is in same domain it will allow. I have a code given bellow which in safari works fine but firefox doesn't display the results when it calls csce server then since the code is on local machine doesn't allow it and returns error. I know it will start working if I load my this code to csce server but I want to run the code from my machine. So can anyone help me in resolving this. I have spent past couple of days just searching for this solution.
Kindly suggest how to achieve this or should I go with some older version of firefox?
I googled and set the parameters of browser in config file as specified in this site but it still doesn't work.

Maybe you could use privoxy and tell it to inject something like "Access-Control-Allow-Origin: *" in the server response.
To do this, you would have to go into the file user.filter (create it if it doesn't exist) in privoxys configuration directory and insert something like this:
SERVER-HEADER-FILTER: allow-crossdomain
s|Server: .*|Access-Control-Allow-Origin: *|
Instead of Server, you can also use any other header that's always present and you don't need.
And this into user.action:
{+server-header-filter{allow-crossdomain}}
csce.unl.edu
Note: I didn't test it.
https://developer.mozilla.org/En/HTTP_access_control
http://config.privoxy.org/user-manual/
This appears to enable XSS from file:// pages in Firefox 4, although it prompts you so might not be suitable for more than simple test pages:
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
I have an app that I'm creating with CakePHP, which rewrites the url from something illegible to most users to something a little easier to comprehend. I'm having a problem when I use the FBML canvas.
When I try to access, say, http://apps.facebook.com/myapp/articles, I get the following error:
Received HTTP error code 404 while
loading
http://www.myapp.com/myapparticles/
I did notice that when I try to access http://apps.facebook.com/myapp/articles/posts, it changes the error to show the following url, which is slightly different: http://www.myapp.com/myapparticles/posts
Which lead me to try accessing it with this: http://apps.facebook.com/myapp//articles, which does work most of the time, though for some reason sometimes it will give the previous error. (And it also seems like a hack-y way of getting it to work).
I'm at a loss for how to fix this.
Turns out I was missing the trailing slash (http://www.myapp.com/myapp/) on the url that I specified as my canvas callback, which is in the app settings. Putting it there fixes the problem.
This happens when you are not using semantic markup or you have an error or some code not supported by fb. Also that famous error is generated by fb when it is down or slow too.
I would suggest you checking your code thoroughly and going through fb documentation. That should help you the most. thanks
