Hi,

I wanted to ask if the same regex used in multiple conditions is the same cached-compiled version? Eg I need to validate the all the (sub)request params before sending it upstream:

location /foo {

if ($time !~ /(\d\d):(\d\d):(\d\d)/) { return 400; } if ($arg_time !~ /(\d\d):(\d\d):(\d\d)/) { return 400; }

}

#note that in the real app, I'll have lots of repeated regex for email, phone, used in every if directive

location /bar {

if ($arg_time !~ /(\d\d):(\d\d):(\d\d)/) { return 400; } set_form_input $form_time time_finished; if ($form_time !~ /(\d\d):(\d\d):(\d\d)/) { return 400; }

What I'm trying to do is send the params to redis with its lua scripting engine handling the *pre-validated* request. Redis is single-process while nginx can have multiple workers ... so its only fitting to let nginx do validation for redis :-)
