Configure session tracking for Wireless Application Protocol devices

Most Wireless Application Protocol (WAP) devices do not support cookies. The preferred way to track sessions for WAP devices is to use URL rewriting. However on most WAP devices, the maximum allowed URL length is 128 characters. With URL rewriting, a session identifier is added to the URL itself, effectively decreasing the space available for the actual URL and the number of parameters that can be sent on a request.

To reduce the length of session identifier, you can configure key (jsessionid), session ID length and clone ID.

Perform these steps to make configuration changes:

1. Start the WebSphere administrative console.
2. Expand Servers.
3. Click Application Servers.
4. Select a server from the list of application servers.
5. Under Additional Properties, click Web Container.
6. Under Additional Properties, click Custom Properties.
7. Add the appropriate properties from the following list:
   • HttpSessionIdLength
   • SessionRewriteIdentifier
   • HttpSessionCloneId
   • CloneSeparatorChange
   • NoAdditionalSessionInfo
   • SessionIdentifierMaxLength

   See the help text for additional information on these Web container custom properties.

8. Click Apply and Save.
