WARNING: This project is deprecated. It rarely works, has been out of date for a long time, and now that CHTTP does not require manually installing dependencies anymore, there is no need to start maintaining this again. The repository and its releases will stay publicly accessible, but unless you have a really good reason for it, you should use CHTTP instead.
gmod-steamhttp
This project aims to provide an open-source drop-in replacement for GMod's built-in HTTP module. It provides the same interface as the original to allow for replacing it easily. In comparison to CHTTP, this module is based on Steam's HTTP backend (ISteamHTTP).

In the case that me including the Steamworks headers/binaries violates some license or anything, please let me know. I haven't been able to find any information about that yet, but I'll happily take them down in case there are any issues.
