I think you may consider replacing webdis with ngx_redis2:
http://wiki.nginx.org/HttpRedis2Module

Also, you may consider replacing SSI with content_by_lua because the
latter provides a full-fledged scripting language as well as the same
nonblocking network I/O capabilities (with ngx_redis2, among other
things).
