I am trying to Monitor a Webpage to make sure it is always running.

The issue I am having is i get redirected to an Authentication Page and I can't get the command to input the Username and Password and redirect me to the webpage

Entering this url - http://urladdress/services Redirects me to here - http://CASserver/urladdress/services and I want it to redirect me back to http://urladdress/services after the user and password has been entered.

The commands I have tried are below and I always get to the login page and do not get redirected after

check_http -I ipaddress -H localhost -u http://urladdress/services -f follow -P "username=user&password=password" -s "you are logged in"
check_http -I ipaddress -H localhost -u http://urladdress/services -f follow -P user:password -s "you are logged in"
check_http -I ipaddress -H localhost -u http://urladdress/services -f follow -a "username=user&password=password" -s "you are logged in"
check_http -I ipaddress -H localhost -u http://urladdress/services -f follow -a user:password -s "you are logged in"

The reply is always HTTP CRITICAL: HTTP/1.1 200 OK - string 'you are logged in' not found on http://CASserver/urladdress/services

What kind of login page is it? AFAIK, check_http only will accept basic authentication, but I may be wrong.

I am redirected to a CAS (Central Authentication Service) server which uses LDAP.

If I am unable to authenticate is it possible to use check_http to perform a wms getcapabilities request?

What happens if you run it with a -r (match regex)? Can you verify the contents of the page?

It's working fine over here. Here's an example from a core system

Thanks but I have decided to go a different route and have managed to use a GetCapabilities for WMS request

/usr/local/nagios/libexec/check_http -I ipaddress -p port -u "/thredds/wms/storelocation?REQUEST=GetCapabilities&SERVICE=WMS" -s "Automatically-generated field"

Is there anything else you would like help with, or is this resolved?
