There are 2 issues with the way the page request delay is implemented:
1. The delay is applied twice for main web requests (listing pages)
2. The delay is not applied at all for sublink requests.

For some sites MP1-2 causes WebEPG to get blacklisted and prevents it from grabbing any data.

There is a community patch available here: http://forum.team-mediaportal.com/submit-code-patches-mediaportal-tv-server-etc-325/webepg-fixes-delay-bugs-83589/

The patch needs review. We need to make sure that behavior does not change for existing grabbers (otherwise sublinks will be delayed by default 500ms each which will slow WebEPG down to a crawl). We only want to be able to specify a delay for sublinks separately. If none specified, 0 should be used as before.
