Gorilla/Mux Reverse mapping URL - go

I'm new in development. Now trying to learn gorilla/mux router.
The question is about reversed urls.
In gorilla/mux I know we name them with .Name() method and access with .Url().
Could someone explain real use case of reserved URL's(Reverse mapping URL)?
But a few hours of googling didn't help me to find any info about that why we even need them? Will be really thankfull if you could show some practical examples.

Use cases if someone needs.
• Constructing redirects to send to a client - eg programmatically, so you don’t have to fix the URLs in your code elsewhere
• Building examples & tests
• Generating docs

Service worker, caching a graph query request

so I'm getting in the world of service workers, found it complex for my level, and despite I manage to cache my physical files in my vue 3 project. I'm struggling with the way of caching the response from headless CMS, there is a lot information around about in general most of then very old, at the beginning I tried using workbox, then I read that you cannot catch graph response or post response(correct if I am wrong), in addition I was having a lot of issues trying to include the script with the vue 3 project and some error about some array, so ended up building the sw from scratch and it worker pretty well so far. Now I'm facing the issue with the graph response, so far I have read it's not easy which is quite discouraging when u read it from more experienced people. I have found some examples and lot of user asking the same question here some with no response as well, and so far I found an interesting response(3 years old), however I am not sure if this actually applies for my case if is deprecate. He provides a code example, however is not providing information about what exactly does the script, you can see the response here
So I am assuming the URL that needs to be provide is the url to my graph API in this case the one provide for CMS. And the in the variable cachedResponse under the catch, do I need to provide the query variable, meaning the const that I am using to call the graph? I have to mention I am not using apollo nor axios just a normal graph inclusion.
Also when I tried to run this code, at the beginning I got an issue with the script from dexie.js and had mime issue which I tried to correct with some suggestion from here. Which did not work for me. I thought that was my sw cache playing bad, however I cleaned it got same issue.
So so far have been a long way, It seems there is not magic formula, but if I can receive an advice or different approach from what I have been trying so far, would be very welcome. Thank you in advance for the help : )

What do protofiles represent for googles API Linter?

since google did not create extensive documentation for their API Linter and I cannot find anything from other sources, i wanted to ask here.
From what exactly am i supposed to create protofiles and what do they represent?
As I understood, these protofiles get checked for compliance to their AIPs.
I'm interested in creating a automatic prototype (Java) to check for customized API Rules and am thinking about using Protobufer for this goal. Would this be a pragmatic solution?
Thank you!
As I now understand, Googles API Linter isn't supposed to check a API or a different API specification for compliance.
It checks proto files because they are themself the API specification and can be converted to Code. But before converting them they can be checked against rules they have to comply with.
These rules are not in the protofiles (as I initially thought) but in the many GO-files under rules/ .
Please correct me if you read this and find mistakes! Thanks!

Katharsis security + API versioning

I am currently evaluating possibilities, how to write/generate level2+ rest API. I came across karharis and i pretty like the concept and the whole idea how its done seems sound to me. But I have not found answers to these questions:
How to handle security properly. I can imagine that it might get tricky, as JSON api supports traversing to some extent. (out app will run in spring environment, so I suppose that we might use spring-security, but I do not know, if we will encounter some hidden traps)
API versioning. I havent found any clues how to handle API evolution. Are there any already supported options (content negotiation, path variable, query parameter...?) or do we need to hack it ourselves?
Thanks in advance!

Correct place to exend FLOW3 Bootstrap?

currently I am trying to register a Doctrine-Eventlistener for every request in my FLOW3-Package. Some research pointed me to the Package.php, but unfortunately the ObjectManager is not available when the boot()-Method is called.
I searched the whole FLOW3-Documentation http://flow3.typo3.org/documentation/guide/partiii/bootstrapping.html without luck
Any hints on which is the right place to do package-wide setup with access to the object manager?
thanks and best regards
Your are bit to early in the bootstrap to get every object, I have a problem, maybe related to yours, you can check my bug report on http://forge.typo3.org/issues/33838
Why do you need a Doctrine Eventlistener, maybe you can use AOP to have this kind of feature ?

Handle concurrent file download with flex/blazeDs/Spring

I'm currently working on a Flex3/blazeDS/Spring/MySQL project.
In this, some users needs to download some import logs. Problem is that given the singleton concept around spring, if 2 users ask for a download at the same time, the servlet responsible for export file creation may cross content between the 2 asked files.
I'm not that much familiar with spring but from what i've been reading around it seems that the solution lies in saying that the servlet is in "Request" scope so there will be a new one created for each download request instead of having a singleton.
Does anyone have ever done something like this before? Every tutorials i've seen so far explains how to handle file download request but it never talks about the fact that 2 users asking for a download may have some issues...
Thanks for any leads on how to fix this.
Each user will receive his own thread, and you should not have any problems unless using member variables (which is a bad practice anyway). If not, I do not see any problem, but it would help if you can post your code.
