Scenario - using a server side include in a html page. It generates a question and then, based on the answer given, outputs result. Once user has used tool it should only show the result, not the question in that user-browser session. This must all be done by a ssi within the html page, cannot display result on other page etc. Using standard cgi session 'api' doesn't work as the html page has already written the header, so the writing the session cookie to a header in the ssi fails, and appending the session id to the url is not an option. Any ideas ?
