Detect network proxy - currectly for Windows only
Its designed for detecting the proxy once in a while, it doesn't cache internet sessions etc, so it could be relatively slow if you are querying it a lot.
I will be using these with NTLM proxies most of the time.
Compiles for C++, so I can use std::string objects, but could be converted to C.
HOW TO USE:
#include <detectproxy/detectproxy.hpp>
...
string proxy = detectproxy(target_url);Now you can feed the "proxy" into libCurl, it will be something like proxy.host.com:8888
All strings are assumed UTF-8.
Note that to get libCurl to authenticate against NTLM proxies, you must also set user/pass to blank strings "".
Note that detectproxy() will THROW a runtime_error if there is some sort of error.
You can also do:
string proxy = detectproxy(target_url, &std::cout);to see messages during the detection process.
TODO:
- Tests (will need some proxies to test against... how?)
- Improve the proxy list splitting (its very naive at the moment)
- Handle the proxy-bypass list
- Cache the internal internet session - threadsafe?
- Test situation where proxy server does not need or want user/pass.
- Handle WinHttpGetProxyForUrl potential crashes (I have seen mention that old McAfee can cause crashes).
- Test chinese URLs.
