The value of req.mtime is 0.0 just before the meets_conditions call. Although I'm not familiar with the internals of mod_python and Apache, I looked at Apache's ap_meets_conditions, which uses current time as mtime if req.mtime is 0. So meets_conditions is unusable until 3.3? Hmm.... BTW, when will 3.3 come out? _________________________________________________________________ All-in-one security and maintenance for your PC.
