The eval module's handler runs before the ngx_rewrite module. So make
sure you always "set" variables inside the eval block. The "set"
directives outside the eval block does not work because they run after
the "eval" block and hence the memcached handler complete.

IIRC, this was mentioned in the ngx_eval module's documentation.
