Okay, understand now. I didn't notice that you were using mod_python
2.7.10 before.
What you have found is a bug in 2.7.10. Namely, that you will get a 500
server
error if you do not return anything, or return an empty string from the
method.
Add:
return " "
at the end of the method. Ie., string containing a single character and
it looks
like it will work.
Weird. The code works fine on 3.X mod_python. Ie., handles no return
value.
