Context options for Situation elements

Adding a Context to a Situation allows you to define what kinds of patterns you want to look for in the traffic.

For example, you can specify that you want to look for a certain character sequence in an HTTP stream from the client to the server.

When you select a Context, you get a set of options or a field for entering a regular expression as parameters for the Context. The parameters define the pattern you want to look for in the traffic.

Other types of context parameters are not listed in this guide. They concentrate on some aspect of a particular kind of network traffic, and using them requires basic knowledge of the underlying network protocols. For more information on what a particular Context is used for, see the Properties dialog box of the Context in question.

Context elements are protocol-specific, so they define what the Situation element matches. They provide a framework for defining the parameters for each Situation. The parameters are entered as a regular expression or through a set of fields and options that you can adjust, depending on the Context element selected. The properties of each Context help in filling in the parameters for the Contexts.
