I have an Apache web server hosting a number of sites. On some sites there is HTTP Basic Authentication. I allow some hosts access to the site effectively bypassing the HTTP Auth.
Allow from 10.10.
I am now placing a Varnish caching server in front of the web server and now all requests to the web server appear as they have come from the varnish server (192.168.1.101).
The white-listed IP addresses that used to be allowed to access the sites without HTTP authentication are now being prompted for HTTP authorization.
I cant set allow from 192.168 as this effectively allows the entire web access. So my question is. Is there any way I can get varnish to pass the client IP address to the backend server to prevent this from occurring? Or does anyone know another way around this issue? Thanks in advance.
