Thanks for your answer, Christopher.

I would prefer not modifying the interchange server itself unless completely
needed, because that means additional complexity on delivering the catalog:
you have to patch into /usr/lib/interchange, also maintain patches according
to the IC version, etc... The addition of new tags to
/usr/lib/interchange/usertag is the maximum I can afford.

And relating to the system calls, I will also prefer not calling any
external process. This means taking care of additional security risks
(escaping hazardous characters, etc.), and the least permissions I have to
take care of, the best for the delivery process.

Also, if the get-url tag uses LWP and works, why doesn't my tag using POST
instead of GET have to work as well?
