Someone has made a very good implementation of a custom skin server, but never finished it, when you told me to search one, I had to correct it, and finally done it, I will keep updating my fork for all versions you support.
Just an information if someone need it.

how would i go to do this?
do i remove the extension on my custom server?

Either that or make a rule in your web server.

Thanks, after reading a lot of times and experimenting with the things said in this "issue"
i finally figured it out on how to make it work on 1.12.2

again, many thanks lol

I added support for custom server in 1.12.2-v2.
It also has better caching behavior to reduce network traffic.

Thanks ! I was planning to upgrade it to 1.12.2...
So, there is no backports of your own implementation in 1.11.2 / 1.10.2 / etc ? Else I may do it, should be useful.

If you want to do it, i am fine with that.
This current implementation requires java 8, prior versions of minecraft don't necessarily run on java 8, they could be on java 7 or 6.

I could implements a config option for compatibility with prior Java like 7 / 6. This should fix the issue.

@zlainsama >I added support for custom server in 1.12.2-v2.

I came here wanting to ask for this feature and it has already been done, awesome job.

Though this feature is nowhere to be found in the documentation, would you please do the following?

• Add this feature To documentation on CurseForge
• Copy the documentation into a README.md file in this repo so it doesn't rely on CF only

I added one line in project description on curse forge to indicate this feature exist.

I remember I added description in the config file when I was implementing the feature.

They are: (replace example.com with your server ip or domain name)
http://example.com/skins/uuid.png
http://example.com/skins/username.png
http://example.com/capes/uuid.png
http://example.com/capes/username.png

Https is also supported.

Actually that doesn't work, the mod requests the names without the extension. If I remove the extension it works, the mod is awesome ^^

@zlainsama Could you add to the documentation in the cfg or elsewhere what exactly does the mod expect?

I assume it's in the same format as the official server, but a person looking at it won't figure that out without a bunch of googling.
