http client testing

Folks,

        Do anybody have thoughts how to setup a testing environment (with a  
reasonable effort) of http client functionality and how far one can go  
this road. All this in the context of libcurl binding. There are a lot of  
features  ((get, put, post, head) * (ssl, proxy, auth,  
tunneling,cookies)). It is relatively easy to establish a ftp test server,  
but I'm a bit a lost with http. Any ideas?

        Thanks
                Danil
