You question is a bit vague but ...

Make your index_html a python script.  And then stuff your REQUEST with 
info you want

Then just call the Page Template ...

request.set('formvar1', somevalue)
return context.myPageTemplate(context.request)

Of course of you have <forms> submit with an action="." and method="post".

Then you can intercept all calls using index_html, do what you need to 
do and *then* render the next form.
