With regards to your .htaccess file, how big is too big?
As the .htaccess file grows larger, is site performance degraded?
Here's my scenario:
I am building a WordPress 3.0.1 multi-site installation with approximately 100 sites.
All sites are sub-directory sites with their own domain mapped, using the WPMU Domain Mapping plugin.
All sites have W3 Total Cache plugin enabled with CDN and Page Caching enabled.
For each site, the W3 Total Cache plugin generates about 143 lines of code to be added to the .htaccess file. It is my understanding that this code should be added to the .htaccess file - and I will end up with a .htaccess file that is approx. 100 X 143 lines ~ 14,300 lines long. This seems like it would probably degrade site load times in itself.
Or, am I just missing the point about how to configure W3 Total Cache correctly?
