You can but the filter plugin is probably enough. It gives the
capability to route request by looking at the request-uri. The
matching is done with regular expression. There is a sample
configuration in the file filter.c

There is no stateless capability in partysip. It has been
removed since long and there is no plan to add it again.

Right.

The transaction is already created when you receive the request in
the plugin. You can't avoid that. You can improve the tlp plugin
to send some requests statelessy. For sure.

Nothing already existing can do that in partysip.

Partysip is not designed for being a stateless proxy.
That's why it has been removed. In fact, the proxy was
a lot slower when the stateless module was existing...
