C/C++ HTTP Client Library for Embedded Projects
So I have trawled through pages and pages of search results on StackOverflow and Google and I have come across very few C/C++ HTTP client libraries suitable for a resource-constrained, embedded environment (e.g. an ARM). I have however come across quite a few that are suitable for desktop-class applications.
Essentially, I am after a simple, easy-to-use and convenient API to make HTTP GET, POST and HEAD calls (with support for authentication, download resume and payload compression). It would be ideal if it had a small footprint (i.e. no or minimal external dependencies) and is open-source (with a permissive license).
Here's a list of what I've come across so far and why they are not suitable -
- curl - too heavyweight
- poco - too heavyweight
- neon - GPL
- qlibc - relies on POSIX libraries
- cpp-netlib - relies on Boost libraries
- serf - relies on the Apache Portable Runtime library
- urdl - relies on Boost libraries
- HTTP Client C API - promising but requires a C++ wrapper
Are there any libraries out there that I am unaware of or am I better off rolling my own?

Have you taken a look at the HTTPClient on mbed? Looks like there are lots of forks of an original from a few years ago that wasn't maintained. I haven't used this...
