that gets sent through it and this makes browsers switch to "quirks"
mode, breaking expected page layout.

Public bug reported:
Binary package hint: libapache2-mod-mono
In Ubuntu 8.04, libapache2-mod-mono depends on apache2-mpm-worker, while
libapache2-mod-php5 depends on apache2-mpm-prefork, which makes mono and php5
mutually exclusive.
I have just upgraded from 7.04, where this was never a problem
