Forum OpenACS Q&A: Response to no headers from ns_return!?

Posted by Tilmann Singer on
Did you experiment with Pragma: no-cache and Expires: headers? Those two commands worked for me:

ns_set icput [ns_conn outputheaders] "Pragma" "no-cache"

ns_setexpires 0

Also if you have control over the referencing link then you can append a bogus variable with some random value to the url to make sure IE really reloads the page (very ugly though ...)
