I have been attempting to locate the format of a PRPCGateway URL to no avail.
As per RFC 1808 Section 2.1 - URL Syntactic Components ...
... It would appear that the PRPC Gateway URL format is as follows:
scheme://net_loc/prgateway/PRPCGateway/A/!B/$C/remainder of path;params?query#fragment
A = ????
B = Application Name?
C = Thread Name?
If someone is aware of the format and can help fill in the blanks above, it would be very much appreciated.
