Description

Previously, to remove a parameter from a header it was needed to create a complex method on the configuration file for each header/parameter. This modification moves this complexity to the 'pv_headers' module.

Two new functions:

pvh_header_param_exists
pvh_remove_header_param

Both functions take as parameters the name of the header and the name of the parameter.

It returns '-1' if the combination header/parameter:

is not found (pvh_header_param_exists)
couldn't be removed (pvh_remove_header_param).

Examples (proxy configuration):

if (pvh_header_param_exists("Supported", "100rel"))
{
// "100rel" is present on the "Supported" header
}

if (pvh_remove_header_param("Supported", "100rel"))
{
// "100rel" removed from header "Supported"
}
