I am dealing with the http header. it is basically made up of
pairs like teh following:

key: value\n\r
key: value\n\r
key: value\n\r

Now, I need to capture those values and push them into an
associative array, so basically I am going to use std::string
this way:

#include <string>
#include <map>
using namespace std;

map<string, string> header;

Yet, since I am quite new to std::string I'd like to know how
to split one line based on ": ", then I am goit to remove any
extra whitespaces by using my own chomp()

Have you looked at std::find? Something like:

    std::map< std::string, std::string >::value_type
    split( std::string const& line )
    {
        std::string::const_iterator pivot
                = std::find(line.begin(), line.end(), ':');
        return std::map< std::string, std::string >::value_type(
            std::string( line.begin(), pivot ),
            (pivot == line.end()
                ? std::string()
                : std::string(pivot + 1, line.end())));
    }
