Hi everybody.
I'm (trying) to work with Opera, because I love it's speed,
the problem is, from time to time, a request from opera,
(seems to raise on POST only) causes Zope to eat all ram
it can get and all cpu available.
I tried to check out and found following data:
it only rises on POST requests
then it rises on this requests EVERYTIME
I have two files for you, tracing the conversation of an example
post. The first one traces a post trying to create a DTML Method
with opera 5.02 Linux, the second tries the same thing,=20
same urls, with Netscape 4.77.
