How do I warn my users that a given Zope page will take a long time to load? Is there any way to load a preliminary "please wait this may take a while" page while the user waits for the real page to load?
The only way I know of is to use Javascript (although there may be a RESPONSE header you can set).
There is:
<META HTTP-EQUIV="Refresh" CONTENT="3;URL=very_slow_page_html">
Add it to the <head> section of the please wait page. The 3 is how soon after the redirect should happen so you'll probably want to use 0.
I was going to suggest this as well, but I realized I wasn't sure how to get the form data to very_slow_page.html. I guess the original responding page could write it into the meta tag URL attribute, if it were suitable for a GET rather than a POST. Tom P
