MapRewriteDomain with re2 support? #694

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
There are many sites that for logged-in users will use cookie-based 
authentication in a dynamic script to generate in-page content.

For example,

<img src="/dynamicscript.php?foo=bar" />

Where dynamicscript.php checks for an authentication cookie before returning 
the image in question. Enabling MapRewriteDomain breaks this, as replacing the 
above with something like

<img src="http://mycdn.com/dynamicscript.php?foo=bar" />

Will not necessarily result in the same behavior. If I'm not mistaken, there is 
currently no way to prevent this without explicitly enumerating all possible 
configurations except for /dynamicscript.php as separate MapRewriteDomain rules.

I understand it is not desirable to switch everything over to re2 because 
there's a lot more cognitive overhead involved verses simple wildcards, but 
perhaps there is another solution (maybe MapRewriteDomainRe2)?

Thanks.

I've been thinking about this and want to try to solve this more generically.  
Provide a Central Scrutiziner to determine which transformations get applied to 
which resources/tags in which contexts.

I'm adding the use-case from this bug into Issue 689.
