The common wisdom to get the squid cachemgr.cgi to work is to include the in squid.conf. Unfortunately it doesn't seem to work out of the box with cachemgr.cgi.

To view cache statistics, squid can show different stats via the built in cachemgr cgi interface. However, while i can get past the login screen to the menu, clicking on any of the links returns a ERR_CACHE_MGR_ACCESS_DENIED in the log files and a denied access web page.

Using squidclient with the password, on the other hand, i'm able to access the squid statistics, so the problem lies with cachemgr.cgi.

I've tried but it errors out with a page saying there are quotation marks missing from the request.

Following the tcp stream, it seems that squidclient sends the correct password to the squid instance, but cachemgr.cgi doesn't. Is there a configuration step i'm missing?

I've seen recommendations on the web on setting , which is a pretty bad idea. And another which suggested adding , which is also a bad idea.

How can i enable cachemgr.cgi to access the squid stats?

I'm able to get to the squid-internal-mgr pages, primarily because the http basic auth presented by the broweser works. It seems the login screen of cachemgr.cgi to set http basic auth isn't working

Didn't setup the nginx basic auth. However, even after setting up basic auth for the cgi-bin directory, cachemgr.cgi is still unable to access the squid stats. It looks like cachemgr.cgi isn't sending the correct password to squid, because squidclient works and direct access to squid internal stats work.
