Mike, I hear you.  There are cases where you can solve this problem.  But to say that we don't want to add post processing because of performance reasons means you don't understand how the core operates.  It currently post processes every single url in the system, both for content and for system resources in 4 different ways.  My solution would eliminate all of those post-processing functions except for one in the case of RSS feeds and Emails.  And even then you would solve that problem with caching if performance were to take a hit.

I understand that sometimes you can get an organization to change, but you still had to implement an large degree of extra effort that is only available to one specific platform to achieve your goals.  With root-relative URLs those issues disappear entirely.  You are left with one filter for one type of content that is already being filtered with more complexity than what would be necessary with an alternative architecture.

Yes it can be done. I did *exactly* this last year for a central UK government client. Where the same site was accessed internally as http://cms.somesite.gov.uk and externally as http://www.somesite.gov.uk

Incidentally in the same environment there were two other WP instances, test and long term staging at http://test.somesite.gov.uk  and http://test2.somesite.gov.uk. At the flick of a switch (a click of a control panel link), any of the url's could be pointed at a different WP instance. A different click could copy from one to the other: e.g. bring a copy of live
(wp1) into staging (wp2), ready for adding new content, and click - switch www and cms to point to instance wp2  and now that's the live one.

All three instances were also accessible with ip addresses if needed!

The secret is apache proxying and mod_substitute.

And this was a 1.5 million uniques amonth site, with more than 50K feed subscribers, - we really did not wanting be post processing urls in php for those 50K readers.
