No. Each frame will have a URL (they could be the same URL but ignore
that for a miniute).
ie:
<frame src="url1">
<frame src="url2">
Now consider what url1 and url2 are:
- url1 and url2 could point to different servers, eg:
url1=http://www.wierdstuff.com
url2=http://www.strangestuff.com
- url1 and url2 could point to different paths on the same server
url1=http://www.wierdstuff.com/strange/ghosts
url2=http://www.wierdstuff.com/strange/microsoftcustomers
A servlet engine can represent both these scenarios.
eg: a servlet engine doing multiple hosting could recieve requests
for www.wierdstuff.com and www.strangestuff.com - in this case though
the spec states that servlets must be in different contexts.
But in the second case a single servlet could be mapped to:
www.wierdstuff.com/strange/*
and it would recieve the requests for both frames. In this case the
servlet could use:
HttpServletRequest.,getPathInfo()
to establish whether it was being called from:
ghosts
or:
microsoftcustomers
That is the state of things.
What you *can't* do (which I suspect is what you're asking) is
populate 2 frames from a single request.
However, as an adjunct to that consider that most servlet engines
implement HTTP/1.1 and therefore are capable of persistent connections
thus giving you the performance enhancement of a single request
without the hassle.
