MBS( "CURL.SetOptionProxyAuth"; curl; Value )   More


Parameter Description Example
curl The CURL session handle. $curl
Value The bitmask of allowed authentication methods. 15


Returns "OK" on success.


Sets which authentication methods are used.
Pass a number as parameter, which is set to a bitmask, to tell libcurl which authentication method(s) you want it to use for your proxy authentication. If more than one bit is set, libcurl will first query the site to see what authentication methods it supports and then pick the best one you allow it to use. For some methods, this will induce an extra network round-trip. Set the actual name and password with the CURL.SetOptionProxyUsername option. The bitmask can be constructed by or'ing together the bits listed above for the CURL.SetOptionHTTPAuth option. As of this writing, only Basic, Digest and NTLM work.
