Administrate Browser Rules

Here you can influence the order in which user agent rules will be executed by clicking the arrow buttons. These rules can be defined in the layout properties.

Definition

Each client that accesses a web application will be designated with a user agent. Upon each access to the server, the client sends an identifier, the so-called user agent string, to the server. With this recognition code, the client can be identified.

By managing the browser rules, Intrexx can control which layout should be presented for which client. This is important, as various end devices make various demands on the display necessary, such as with the iPhone or BlackBerry.

Example

If a user calls up the Intrexx portal with their iPhone, the browser of the iPhone will transmit a user agent string to the server, such as Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16.

In the Intrexx portal, the user agent string will be compared, item by item, with the user agent rules in the browser rule manager. The user agent rules are defined via regular expressions, which present a pattern for the possible user agent strings. If a match is found with a user agent rule, the layout linked with the rule will be shown on the browser of the iPhone.

A click on Show Details will open a dialog, in which you can access further information like for example the GUID of the user-agent and the name of the layout.
