URL-based Applications

URL-based applications are extensions to the list of applications. When the URL in an HTTP request (a URL on any port that is part of the iana-l4:http protocol, or protocol named “http” under the “iana-l4” engine ID) matches the criteria of a URL-based application, the traffic is classified as that protocol. The device interface statistics are collected by regularly (once a minute) polling the ifTable statistics of all interfaces on the managed device.

A URL-based application can be used the same way as any other application. For example, a URL-based application can be used in collections, captures, and reports.

An incoming URL is matched against the criteria of the configured URL-based application, in the order of the index, until a match is found. When a match is found, the remaining URL-based applications are not considered.

A URL consists of the following parts:

•a host

•a path

•an argument

For example, in the URL http://host.domain.com/intro?id=123:

•the host part is host.domain.com

•the path part is /intro

•the argument part is ?id=123

In the configuration of an URL-based application, the path part and the argument path are combined and called the path part.

Note The match strings of the URL-based applications are POSIX-limited regular expressions.

Note A maximum of 64 URL-based applications can be defined.

To create a URL-based application from a collected URL:
