if someone would shed light on how subrequests are concatenated to the parent request and send to the client it'd be much appreciated. currently i have been able to issue a subrequest and have verified both the parent request and subrequest successfully return a valid response.

what happens now is that neither the parent request or concatenated subrequest are returned to my browser. an empty request is returned to my browser after waiting for a response for up to 60 seconds.

i've looked into the addition and echo modules which were of great help, any other pointers you may have would be much appreciated.
