I'm not sure if this has been asked before but is it possible to do away with post_info.asp and integrate the post functions within topic.asp and post.asp in order to speed up the posting of posts?
When a person makes a post the forum then opens up the page to thank them for their contribution, then auto refreshes to take them back to the page where they came from. If this page could be taken out of the system it would dramtically improve the speed of posting bearing in mind more and more people are using hand helds and phones for browsing, hence slower speeds
taking the page away would not make any diffference since it would still need to do a post back before redirecting, which page actually accepts the post back (topic/post/post_info) is largely irrelevant.
you could reduce the redirect timer so that it happens quicker, can't remember what the default is, but you can shorten or even remove the timer and redirect as soon as the post has happened instead, would save a few seconds.
