feature request: cache transformed value

[liudongmiao]

In our case (180 rules), after cache, the performance increase about 5% - 10%.

Currently, we use a map on Transactions, and the key is key + path.

This is actually something that I've thought about for some time, as I know at least some other WAFs do something akin to this.

[liudongmiao]

Would this be an option?

[liudongmiao]

If it's not an option, I can add a PR (I have completed).

If it's an option, it's hard for me to define directive.

What about the SecCacheTransformations directive?
