Hi, I have a page with session data transferring through the URLs, so the page URLs in browser look like http://www.mysite.com/_ZopeId/84525053A0xJuPCpTSI/mydir/mydocument. Now, let's have DTML document called "content" inside the "mydocument" folder, which contains some "static" HTML data (this data cannot be DTML, because it needs to be editable with some WYSIWYG editor). Above these folders is some ZPT template called index_html, which will display the content data inside the some template. Let's have some link in the "mydocument/content" document, which is for example <a href="other_document">Link</a> . It is inside the content area and it is linked *relatively*, so I suppose it should maintain the session data (so the Zope's result URL would be http://www.mysite.com/_ZopeId/84525053A0xJuPCpTSI/mydir/other_document ). But the reality is bad - result URL is only http://www.mysite.com/mydir/other_document and the session data is lost. So, the question is, is there *any* way how to maintain URL sessions when linking relatively inside plain content (non-DTML and non-ZPT) document in Zope? Or, if not, how people use to solve this problem generally, when need to transfer non-cookie session data through static <a href="..."> URLs? Thanks for the answer, Lubos.
