Paul,
I'm happy with using the working method over HTTP, but any ideas why HTTPS works only outside of pca?
It's hard to guess what's going on from here. As I understand it, wget via HTTP and HTTPS works on the command line, but doesn't from the pca proxy, unless you set "wgetproxy" in pca-proxy.conf. If that's correct, I assume that you have set the http_proxy environment variable (used by wget) in your shell profile or in ~/.wgetrc, but not for the user (webservd, maybe) which runs the http daemon and therefore the CGI script (the fact that wget just hangs when run from pca-proxy.cgi is a strong indicator that it's being blocked by your company's firewall, too).
If usage of your company proxy is *required* for all connections, it's probably best to set http_proxy in /etc/wgetrc for all users.
If this is not the cause of the problem, please re-run the command you mentioned above with --debug added and post the result.
Martin.
