The implementation of the resolution of #EZP-24854 is breaking the http purge in case the controllers use several X-Location-Id.

curl -I http://mysite.com/myaction

HTTP/1.1 200 OK
Content-Type: text/html; charset=UTF-8
Cache-Control: public, s-maxage=31536000
X-Location-Id: 65,6454,7237,12324787

BAN request for 7237:

X-Location-Id: ^(978687|123|7987|7237)$ 

=> The BAN request won't match the content delivered from /myaction.

I guess the issue raised in #EZP-24854 would be easier to tackle from varnish configuration.

Is it possible to revert the commit?
