Re: High-volume mod_perl based ecommerce sites?
Bjorern's statements below are consistent with my experiences with perl. Our web sites which number around 10 (that I have been involved with in some capacity) typically number around 50K lines of code. We use perl exclusively. Experience, modularity and change control can go a long way. I have noticed no increase in the 'spagetti quality' since converting to mod_perl. Thomas S.

Re: Do I need to reinstall mod_perl?
It looks like /usr/local/lib/perl5/site_perl/5.6.0 needs to be in in @INC If this is your problem, there are several options that might work, #!/usr/local/perl -I/usr/local/lib/perl5/site_perl/5.6.0 or move the .../site_perl/5.6.0/Apache directory to a directory in @INC.

Re: I'm missing something in Apache::Cookie (fwd)
from the looks of the code you guys posted, I would guess that
Cookie->fetch returns a hash reference, not a hash. Could this be the
problem?
