Varnish Cache with PHP Captcha for Anti-Site-Scrapping Algorithm
问题 I've got Varnish cache working with PHP Captcha but I don't understand yet how I can set the trigger limits. After the limit of so many requests per hour (or minute) the captcha input is sent. I have it working but would like to be understand how I can alter the req/s limit. Here is the code from: http://drcarter.info/2010/04/how-fighting-against-scraping-using-varnish-vcl-inline-c-memcached/ What is this code saying to me? if (rc == MEMCACHED_SUCCESS) { uint64_t intval; rc= memcached
