Nimbostratusmonitor web proxy
Hi,
I am currently monitoring 2 web proxys using LTM using tcp/8080.
Best would be to http get www.hp.com for instance using individual proxy ips and associated NTLM credentials ...

NimbostratusI spent a long time trying to work out why the standard HTTP monitors didn't work for this.
 
It is because the HTTP monitor relies on receiving a "401 Authenticate" message from the initial BASIC auth request to kick in the NTLM negotiation.
 
Because proxies respond with a "407 Proxy Authenticate" instead of a 401, the monitor doesn't work.
 
So I wrote the following external monitor: https://devcentral.f5.com/s/articles/ntlm-authenticated-proxy-external-monitor-1013
