I have a search page for one of my web apps that works fine on IIS6 with any amount of search results. In IIS7, when there are a lot of search results (no exact numbers yet), the page that gets returned to the browser is only the last half of the page - the entire <head> section and most of the <body> is missing. If there are fewer search results, the page is sent whole. This makes me think it's a response buffer issue, but the information I'm finding about IIS7 response buffers is that the default setting is something like 4MB, and this page is nowhere near that large. Also, it seems weird that the first half of the page is being truncated, rather than the last half. It would seem that if a buffer was full, you'd get the contents of the buffer up to the point that it was filled, and the rest would be truncated. Maybe that's not how HTTP buffers work? Anyway, any ideas on what this might be, and what I can check? Thanks.
