Re: Looking for documention on deploying roundup with mod_wsgi

Hi Thomas:

Thanks for the notes, I have a few questions.

I am using your wsgi as the example wsgi script for the WSGI Handler
section since it seems the script that was there was broken. I like
the ability to shut off the script for maintenance.

It has been a while since I used apache, so a few questions on the config.

Listen at port 80

I assume this allows apache to directly serve up static files like css
etc rather than going through the wsgi roundup instance?

Remap /foo to /foo/ I assume?

This makes /foo run the wsgi script and pass remaining url path
to the wsgi as path info and query args?

Do you have an example stanza to enable https?

What happens if you don't turn off default?

Gotcha so far.

>/srv/roundup/foo/ contains the Roundup instance and the file
>roundup.wsgi:

This line I don't get. Does apache or mod_wsgi automatically cd to
/home/roundup-foo and how does it know to start there?

>        application = RequestDispatcher(tracker_home)

and magic happens....
