Forum OpenACS Q&A: Response to returning pages in "chunks"

Hmm, I think my question is not specific enough ;)

The problem at hand is...I have a big database query that takes some time. The user doesn't get to see anything till the tcl page has run through. Then ad_return_template is being invoked and the html is being generated.

I want that "one-off" thing to be broken down into chunks, ideally like this:

• return some information
• loop through the database query's result and return it in chunks
• return some more information.
