mod_python, COM, on win2k3 server

I have an application that runs on mod_python/apache using the publisher
handler. It uses an access db as the backend and connects via ADO. In a
test environment on XP it runs fine, but when on a win2k3 server it will
load one page, but all subsequent page loads throw a
pythoncom.CoIni tializeEX error until I restart the apache.

Presumably, this is a threading issue, but I am not sure what the best
approach to fixing it is. Should I simply wrap all COM calls with
pythoncom.CoIni tialize/pythoncom.CoUni nitialize calls, or is this somethig
that needs to be done at a lower level.

This is mod_python 3.2, Python 2.3.5, apache2.0.*, win2k3, ado 2.8, and the
server has 2 processors in case that matters.

Thanks,

Some details, and this is weirder than I thought.

It is working fine with internet explorer or mozilla as the client, but only
crashes with Firefox. Moreover, even while firefox is getting errors, IE
stilll works fine.

The error I get is:

Mod_python error: "PythonHand ler mod_python.publ isher"

Traceback (most recent call last):

Howdy all, I'm working on a web application that is starting to gain a lot of back-end code written in Python. However, all the current interface code is written in legacy PHP. I'd like to slowly introduce new features as Python WSGI programs. Is it possible to write a Python WSGI program that talks to a PHP program as its "back end"? Where can I find out how to do this, preferably with examples?

Hi I'm still a newbie when it comes to web applications, so would like some help in choosing a solution to write apps with Python: What's the difference between using running it through mod_python vs. building an application server using Python-based tools like CherryPy, Quixote, Draco, etc.? Thanks.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
