=====Check status of http(s) site=====
// Tested with Nagios Core 3.3.1 on OpenBSD 5.1. AMD64 //
====By hand====
Check for redirection on <nowiki>www.domain.com</nowiki>:
<code>
/usr/local/libexec/nagios/check_http --hostname=www.domain.com --expect="HTTP/1.1 301 Moved Permanently"
</code>

Check for HTTP Status 401 Unauthorized on <nowiki>https://portal.domain.com</nowiki>:
<code>
/usr/local/libexec/nagios/check_http --hostname=portal.domain.com --ssl --expect="HTTP/1.1 401 Unauthorized"
</code>

Check for the presence of the string "Type your user name and password." on <nowiki>http://login.domain.com/</nowiki> and <nowiki>https://login.domain.com</nowiki> and follow redirection:
<code>
/usr/local/libexec/nagios/check_http --hostname=login.domain.com --string="Type your user name and password." --onredirect=follow
/usr/local/libexec/nagios/check_http --hostname=login.domain.com --ssl --string="Type your user name and password." --onredirect=follow
</code>

Check for the presence of the string "XenApp" on <nowiki>http://apps.domain.com/</nowiki> and <nowiki>https://apps.domain.com/</nowiki>:
<code>
/usr/local/libexec/nagios/check_http --hostname=apps.domain.com --string="XenApp"
/usr/local/libexec/nagios/check_http --hostname=apps.domain.com --ssl --string="XenApp"
</code>

Check for the presence of the string "MySomething" on <nowiki>http://app.domain.com/app1/</nowiki> and <nowiki>https://app.domain.com/app1/</nowiki>:
<code>
/usr/local/libexec/nagios/check_http --hostname=app.domain.com -u /app1/ --string="MySomething"
/usr/local/libexec/nagios/check_http --hostname=app.domain.com --ssl -u /app1/ --string="MySomething"
</code>

For other check_http options examine the output of:
<code>/usr/local/libexec/nagios/check_http --help</code>

====From Nagios====
Define the following command:
<code>
define command {
    command_name    check-url
    command_line    $USER1$/check_http $ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$ $ARG7$ $ARG8$
}
</code>

Define a service using the arguments from the by hand examples above:
<code>
define service {
    use local-service-norenotify
    host_name localhost
    service_description www.domain.com http redirect
    check_command check-url!--hostname=www.domain.com!--expect="HTTP/1.1 301 Moved Permanently"
}
</code>
Seperate each argument with a "!". Replace localhost with a placeholder hostname. \\
// You can probably get away with check-url!all_arguments_without_!_separator, but this was not tested. //
