Hullo! I'm sure this will be obvious to some, but it took me the best part of a morning to figure out so I thought i'd post it anyway... I had a problem with Netscape (on linux) going into an infinite loop looking for a stylesheet when retrieving a non-existent url from zope. Here's why: Imagine serving up a page on http://127.0.0.1:8080/foo/bar <html> <head> <link rel="stylesheet" href="style.css" type="text/css"> </head> <body> <p> This is the index_html Document. </p> </body> </html> split up into standard_header_html and standard_footer_html as expected. Now visit a non-existent url eg http://127.0.0.1:8080/fu/bar Zope now serves up standard_error_message eg <dtml-var standard_header_html> oh dear, an error has occurred... <dtml-var standard_footer_html> This causes Netscape to retrieve http://127.0.0.1:8080/fu/bar/style.css which of course it can't find, so it tries again, and again.... (_duh_) So the moral of this story: - In line you style sheets? - use an absolute link to style.css not a relative one? - have a more independent standard_error_message page? - get Zope to redirect to a standard error page rather than inherit it? Hope someone finds this useful! regards, Chris.
