Thread: Help with porting some Perl code to C

I have this perl script that sends some headers and sends basic authentication to a url and then gets an xml file. I need to port this code to C, but i am unsure of how to send a GET http request with headers and basic authentication

Here is the PERL code

Code:

 # Set up the header information for the request
my $headers = new HTTP::Headers
 'Header 1'                =>      $client_retsver,
'Header 1' =>      "Digest ".$client_retsauth;

my $ua = LWP::UserAgent->new;
$ua->agent($client_agent);

#my $request = HTTP::Request->new(GET => 'http://www.url.com', $headers);

$request->authorization_basic($user_userid,$user_password);

my $response = $ua->request($request);

Anyone have any ideas on how to port this over to C - is sockets the answer?

Well what i am doing is modifying a CGI already written in C - this is just a small portion but highly important part that needs modifying. This is my reason. I realize that perl would be the ideal language, but i can not rewrite the software in perl....i havent done much with sockets...any idea how i can setup a socket and then send the headers, do authentication and then recieve the file from the url?
