A problem with image caching affecting certain versions of Netscape browsers browsers

I missed any reference to it on the list and have been unable to locate anything in various archives. I have just such a problem and I hope this is a fix.

The problem was related to Netscape browsers on Win32 sending If-Modified-Since headers with dates like "15-Mar-00" when they meant "15-Mar-2000". This caused two problems in Zope. The DateTime module reinterpreted the date as "15-Mar-1900". This has been fixed in the CVS version of the module where years of the form 00-69 are now interpreted as 2000 + 00-69. The second problem ocurred in OFS/Image.py where the date was turned into whole seconds with Python's int() function. Dates so early lead to float numbers that exceed the range of numbers int() can deal with. This is also fixed in the current CVS version. ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres@corrada.com ------------------------------------------------------
