I want to change a website from using frames to ssi..

Situation:
mainform.html has 2 includefiles using (php)SSI, search.php and search_result.php.
search.php has a form where search criteria can be given, the result I want to show-up in another part of the page without having to reload the hole page again.. When using frames I can set the target of the form-tag to "frame" but now I want to (re)load search_result.php in the current page using SSI..
Or should I use something else, can CSS play a part in this?

I've searched the web for ours but can't find a solution..

Mark.

If you have an include page then, you won't be able to make only 1 include page reload an not the other.

Can you give me some hints on what options I have?
I really want to leave frames but I do want independent (and updatable) pages on ONE page..
I understand SSI is an alternative for including pages, I already do this for a header/footer etc..
But how can I update an individual (sub)page? Reloading the hole thing means I have to resubmit querydata to other pages also, seems to be a little overkill..

Thanks.

What to you mean by resubmit querydata?? Is it a search page you're creating write??? Then all you have to do is use GET instead of POST. GET will simply retrieve the param parsed in the link.
