22.5 Handling Firewalls

If your application must first connect to a firewall machine, and have the firewall to forward HTTP requests, you may be stymied at first. However you can easily do this in a manner similar to the code snippet below. The trick is to realize that the "path" part of an HTTP request can include the full URL.

 
    RWIHttpClient hc(RWIHttpVersion_1_0());
    RWCString real("www.goodlocation.com/goodstuff");
    RWCString firewall("firewall.worried.org");
  #if defined(HAS_FIREWALL)
    hc.connect(firewall,firewallPortNumber);
    // ... maybe other stuff here
    hc.execute(RWHttpGet("http://www.goodlocation.com/goodstuff"));
  #else // no firewall
    hc.connect(real);
    // ... maybe other stuff here
    hc.execute(RWHttpGet("/goodstuff");
  #endif
