[SR-Users] Decoding HTTP URLs in event_route[xhttp:request]

[Peter Dunkley]

Hello,

I have added a transformation to the xhttp module that breaks a URL into a
path and a querystring
- {url.path}
- {url.querystring}

I have also added an optional delimiter parameter to the {param.}
transformations.

Regards,

Peter
