theTrasher - Looking up the UA I've quoted leads via user-agents dot org to wiki.apache dot org which defines the initial proposal and adds a link to synapse.apache dot org which gives the definition in my OP.
It is quite possible that the Pascal/etc library is a wrapper around the Apache code or a fork of it - this would make sense. Both versions support both linux and windows ON APACHE. If it's the same then the feature "How to connect using GET to get page or send data to a server" is very disturbing!
Synapse (both) seems to use Java, which is currently an exploitable app that people are being recommended to disable. Hmmm.
There is an associated User-Agent of "Axis2" in the original synapse.apache documentation but this seems to be for the SOAP client.
bigtoga - I have not seen that scenario. It is quite feasible for different operators to run different operations, though. Do you allow the UA to read your pages or do you return (eg) 403?
