Redirecting the Web Server

Use

It is possible to redirect the task of displaying content to different locations via a Web server.

The Web server can be specified via the document space or by means of the logical document class. In this case, the logical document class has a higher priority, that is, the Web server defined for the logical document class is used to display the content. If, on the other hand, no Web server is defined for the logical document class, the Web server defined for the document space is used.

To enhance performance, accesses to a Web server can be redirected to a Web server near the client. In order to do so, however, you must define locations (see Locations).

The following are required to redirect the Web sever:

• Locations must be defined (see Locations)

• The subnets must be defined (see IP Subnets)

• The host locations must be defined (see Hosts)

• The Web server must be defined for logical document classes (see Web Servers for Document Classes)

• The Web server must be defined for document spaces (see Web Servers for Document Spaces)

Process

On the original Web server, the IP address and logical document class are mapped to the new Web server in two steps:

1. The IP address is mapped to the location

   This is carried out by means of the subnet definition for locations (see IP Subnets).

2. The location and logical document class are mapped to the Web server

   Use the following rules to determine the Web server (the first one with a successful result applies):

   1. Is there a special Web server for the given combination of location and logical document class?

   2. If this is not the case, is there a standard Web server for the logical document class?

   3. If this is not the case, is there a Web server for the logical document class?

   4. If this is not the case, is there a special Web server for the relevant combination of location and document space?

   5. If this is not the case, is there a standard Web server for the document space?

   6. If this is not the case, is there a Web server for the document space?

   If points c) or f) apply, the original Web server is used as the redirect Web server, since the original Web server is stored here. If the display request was not sent to the original Web server, the request can thus be redirected to the original Web server.
