Browser rules

By managing browser rules, Intrexx can control which layout should be provided for which client.

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

Example

If a user calls up the Intrexx portal with their iPhone, the iPhone's browser transmits a user agent string to the server, e.g.

            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

Layout settings - layout output

In the Intrexx portal, the user agent string that the client sends to the server is compared sequentially with the user agent rules from the browser rules management. The user agent rules are defined in the layout properties by regular expressions that represent a pattern for the possible user agent strings. If a match is found with a user agent rule, the layout linked to the rule is displayed in the iPhone's browser.

All user agents are listed here in the "Output" area.

Select user agent / Edit user agent

Opens a dialog in which a user agent can be selected or edited.

Description

Enter the name of the user agent here.

Select user agent

A submenu will appear where a user agent can be selected.

User agent (Regular expression)

Enter the regular expression for the user agent here. If you have selected a user agent via the submenu, the expression is automatically entered here.

Delete user agent

If changes have been made to the user agent rules in the meantime, e.g. because a layout has been edited locally, a message dialog is displayed when the layout properties are opened.
