Is there anyone that has tried NGINX captcha in 2.6.x?
We are working on collecting feedback for Nginx captcha. We will keep you updated.
Will the installation interfere with other services on the server?
We repacked nginx captcha binaries separately from default nginx package. No package name, config, serving port or path conflicts are expected.
Will it reduce load in general on the server? Anyone tested it on a DoS attack?
How much faster is it then using apache for loading it?
Thanks Igor Savenko for the above reply post. I hope that reply post answers your question.
