Improvement:
Add a switch to allow redirection to be followed with depth, -dN with N = 0 for infinite redirection, or N > 0 for N redirection
It would be nice to be able to keep the socket alive if the server answers with a keep alive header.
The syntax would become:
$urlget([id],url,gpfbrtcdN,target,alias,headers,body)
and if "id" is specified (which can be easily recognized from an url), then the same socket is used if one is already in use for that id, (otherwise either use the id "passed" as the id "returned" if possible (and error out if already in use) or just ignore the id parameter and create a new id).
