[#35231] - joomla 4 extensions download fails when URL redirects

I'm managing the embedchessboard extension, it works great on joomla 4 apart from an installation issue.
The extension is registered on the joomla extension directory to support the web install option.
The download URL was fully working on joomla 3.x
http://downloads.sourceforge.net/project/pgn4web/embedchessboard-joomla-plugin-3.05.00.zip
This is the URL on sourceforge that will redirect to one of their mirrors.
The web install on joomla 4 gives an error, about missing the manifest file, that means it did not download the file correctly. Same passing the URL above to the "install from URL form".
If instead I use the actual mirror address in the "install from URL form", it all works:
https://kumisystems.dl.sourceforge.net/project/pgn4web/embedchessboard-joomla-plugin-3.05.00.zip
Something changed from joomla 3.x to joomla 4 that does not like URL redirects when downloading an extension. Is this intentional or it's a bug? How do I report this issue for a fix?
Thanks.
PS: temporarily I changed the web install URL to restore the functionality, but it would really be great to get it back to work as in joomla 3.x

Joomla doesnt handle a 307. Joomla will only handle a 302 Found redirect.
"Joomla doesnt handle a 307. Joomla will only handle a 302 Found redirect."
it used to work in joomla 3.x... any chance of restoring the functionality?
In a way, it makes sense to use the temporary redirect because sourceforge uses a pool of mirrors, so requesting the same URL at different times might result in a different mirror being selected and a different final URL.

In fact when testing Im getting a 200 OK header now... with no body..
Investigating.
It seems I haven't checked for a while... I just spotted the issue now doing some checks on joomla 4.
Still, would there be any issue in handling a 307 response in the same way as a 302 response?

Weird, but I have very little chance of changing sourceforge behaviour.
Such a pity that the joomla extension directory does not offer the possibility to pull the extension from their server...

sourceforge is just trying to protect against leeching... its now giving me different responses each time.
Ok I have it stable now.
The first call is a 307 redirect which it seems Joomla (somehow) is following.
This redirects me to https://sourceforge.net/projects/pgn4web/files/embedchessboard-joomla-plugin-3.05.00.zip/download?use_mirror=kumisystems
That is a 200 OK response with a full HTML page.
Sourceforge is not giving us any Zip file url to download - it gives us a 200 OK with a HTML page.
This is Sourceforge protecting against leeching and automated downloads.
This therefore cannot be fixed in Joomla..
It should also be noted that if you do all this at the command line with Curl you will first get a 302 and then a 200 with the zip file contents.
The conclusion seems that I need to find another host for the download package of my joomla extension :-(
Thanks for looking into this!

Sourceforge is so 1990s anyway :)
GitHub is the way to host code now :)

Closing as not a core issue.
If you try in the extension "Install from URL" form, both
http://downloads.sourceforge.net/project/pgn4web/embedchessboard-joomla-plugin-3.05.00.zip
and
https://downloads.sourceforge.net/project/pgn4web/embedchessboard-joomla-plugin-3.05.00.zip
fail.
Only the last URL works, the one that does not redirects anymore:
https://kumisystems.dl.sourceforge.net/project/pgn4web/embedchessboard-joomla-plugin-3.05.00.zip
It might be that sourceforge is doing something funny... but it used to work without a glitch in joomla 3.x
