Holger,

In your case I would suggest checking the url yourself to see if it is one that is part of some list (one that you could
read in from a text file to keep it configurable), prior to making the curl calls, since you know which sites require
the proxy and which ones do not.

I understand that curl does not perform a check for whether a proxy is required or not.

I need similar capability but I do not know ahead of time if proxy information is required or not. I may just run the
curl connect, and if it fails, then try again using proxy, and if it fails this time, then return an error code.

Adding a proxy check to curl would be a good project.
