I ran into a wee problem which took me ages to solve, so I thought I would share it in case you have it too (and don't know) or a better solution. So: I am developing a site and have exUserFolder for authentication purposes. I also have an experimental site for testing developments that are likely to go wrong. The development site is using Zope 2.5.1 and everything works nicely. The experimental site had Zope 2.6.1 installed and it seemd to work nicely too. Except that if the web browser happened to be Netscape 4.7 then the exUserFolder refresh page hung (i.e. no Refresh). Also, if the browser happened to be Internet Explorer 5 then a Server Internal Error 500 was reported. All I could find in the mail archives was a reference to older browsers not implementing Refresh reliably. So why should the same browser work with one site and not the other? I noticed that in 2.5.1 the refresh page has Traceback information as a HTML comment, but that in 2.6.1 the Traceback has been moved to the error log. So putting about 900 hidden characters in the Refresh body makes NN4.7 and IE5 work again. with 2.6.1 For the record, I just added <!-- xxxx .... xxxx --> to the body of Products/exUserFolder/dtml/docLoginRedirect.dtml Cliff _______________________________________________________________ Dr C.E.Ford, Senior Lecturer in Geology Grant Institute of Geology and Geophysics Telephone (+44) 131 650 4838, Fax (+44) 131 650 5738 http://www.glg.ed.ac.uk/people/academic/FordCliff.html
