Thank you for your response. You are not missing the point of my questions. But I do not really have control over the requests. Or rather, I do, but there are hundreds of pages containing hundreds of similar (but not equal) links, and it is in the practice not doable to edit them all.. And my "" URI was an oversimplification for the sake of this post. The real URI for that first frame is more complicated to generate, and beyond what I can do with mod_rewrite et al. But second, I just realised that I cannot do things the way I explain below anyway, because inside a tag, you cannot put content. You can only use . So basically, my skeleton ResponseHandler works as I expected and does create the document that I wanted and returns it, but that document is invalid html. Shucks. Back to the drawing board. Which now creates another issue : I could create instead a document like : but.. the URI of the request for the second frame would trigger my ResponseHandler again, and I'd be stuck in a forever-loop of embedded frames, fractal-like. So now I am going to re-read your suggestions below, and see if I can figure out something along those lines which does not force me to edit and/or rename all the pages. Maybe instead of generating the second frame as I can instead generate it as and then detect this in the Handler, change the $r->uri back to the correct one, and let Apache's default handler serve it by returning DECLINED. I'll try that.
