Subject: RE: [xsl] Using output URI resolver within a servlet From: "Michael Kay" <mhk@xxxxxxxxx> Date: Mon, 12 Apr 2004 22:55:22 +0100 |
Using IFRAME implies you have multiple HTML documents with different URIs. You can't (as far as I know) deliver multiple HTML documents with different URIs in response to a single HTTP request. I may have misunderstood what you are attempting, but it sounds as if this is what you are trying to do.
