See some of previous rants for possibly useful about this. http://www.modpython.org/pipermail/mod_python/2005-August/018828.html http://www.modpython.org/pipermail/mod_python/2005-August/018829.html http://www.modpython.org/pipermail/mod_python/2006-March/020501.html > whereas with > > <Directory '/your_document_root/whatever'> > AddHandler mod_python .py > PythonHandler mod_python.publisher > </Directory> > > you would need http://yourserver/whatever/foo.py/bar As long as you have content negotiation directives set correctly, you don't have to use .py extension when AddHandler is used. See my linked rants above for details. > So it's really up to you which behaviour you like, you want *all* > files to be served by mod_python or only those that have a specific > extension and then you set either AddHandler or SetHandler.

If using AddHandler and Apache has write permission to directory, it is actually a good idea to have: <Files *.pyc> deny from all </Files> This will prevent the pyc files being accessible. Using AddHandler for pyc extension will probably actually cause it to execute the file as publisher, just like if py extension was used. This is because mod_python.publisher will quite happily drop the pyc extension and use basename to match to .py file. Besides the fact that AddHandler allows you to mix other file types in the same directory, the main difference between SetHandler and AddHandler as far as mod_python.publisher goes is that when SetHandler is used a request against the directory is passed through direct to mod_python.publisher and it resolves request to index.py. When AddHandler is used, a request against the directory results in mod_dir trying to match for a file listed in DirectoryIndex directive. In order for mod_python.publisher to be triggered, you would need to list index.py in the DirectoryIndex directive. Other than that, with the correct Apache directives defined related to content negotiation, both ways should allow for optional use of extension. Graham |
