No, but you can use existing operators to achieve the same (ezsys+ezurl). But you make me wonder why you would need to? Reverse proxies without dns tricks?
The reason why I need to do this is because of an integration with paynet which makes use of a template built by eZPublish. Without absolute URLs, the paynet domain is used as the basis of links instead of our own.
Could you please give me a quick example as I can't get it to work. Thanks in advance!
