LTM Rewrite Profile - Is there any way to make the matching case-insensitive?

I recently ran into the same situation.

A customer asked for a -nocase clientside REWRITE to a highly MiXed- and strickly cAse-SenSitiVe serverside.

I ended up attaching a RULE_INIT iRule to each VS holding an abstracted syntax how the REWRITE should look like.

Deployed in the background a iCall script to read the abstracted syntax out of those iRules on each saving to recalculate the required REWRITE profile and to construct a [string map -nocase] replace list for a rather simple HTTP_REQUEST iRule to allign the case of the clientside path portion.

Pretty overkill, but in the end it has worked out and was also easier to maintain than a usual REWITE profile... ;-)
