Setting memcache keys in eval block

Thank you for your quick answer, although it is not quite a satisfaction to 
read it's not possible at the moment.

How can i stay up to date for such a feature if it were to be implemented in 
the - hopefully nearby - future?

I have another question, is my current solution really much slower than doing 
it all in one location directive? I am now proxying the request the myself 
where i can set the second eval block.

I did perform some simple benchmarks but they aren't really alright since i 
cannot really compare the situations but 2 http requests + 2 memcache requests 
are quite slow in the end.
