Adding a Variable is a compelling feature that will allow you to extract data from the request and utilize it in the Actions. For example, you could log a user username or send an email if there is a security problem.
Variable: This must start and end with a $ symbol. For example $variable1$
Source: Select from the drop-down box the source of the variable
Detail: Select from the list when relevant. If the Source=Request Header, the Details could be User-Agent
Value: Enter the text or regular expression to fine-tune the variable.
Built-in Variables:
Built-In variables have already been hard coded, so you do not need to create an evaluation entry for these.
You can use any of the variable listed below in your action
The explanation for each variable is located in the “Condition” table above
o Method = $method$
o Path = $path$
o Querystring = $querystring$
o Sourceip = $sourceip$
o Response code (text also included “200 OK”) = $resp$
o Host = $host$
o Version = $version$
o Clientport = $clientport$
o Clientip = $clientip$
o Geolocation = $geolocation$”
Example Action:
Action = Redirect 302
o Target = HTTPs://$host$/404.html
Action = Log
o Target = A client from $sourceip$:$sourceport$ has just made a request $path$ page
Explanation:
A client accessing page that does not exist would ordinarily be presented with a browsers 404 page
In this instance the user is redirected to the original hostname they used but the wrong path is replaced with 404.html
An entry is added to the syslog saying “A client from 154.3.22.14:3454 has just made a request to wrong.html page”
