7. Click the Finished button.

Optional: Creating persistence profile

Persistence is essential in an application server environment, especially in

Java environments managed by Tomcat. For every user session, memory

space is allocated on a particular server, so returning a user to the same

machine, creates efficiency for both the server and the user.

For Tomcat persistence, there are two options. If the only persistence being

used by your application is based on jSession cookie, the BIG-IP system's

built-in cookie hash method can be used to maintain persistence. If URI

based session persistence is also used, then it is our recommendation to use

the BIG-IP system’s Universal Inspection Engine.

To create a new cookie persistence profile

1. On the Main tab, expand Local Traffic, and then click Profiles.

The HTTP Profiles screen opens.

2. On the Menu bar, click Persistence.

The Persistence Profiles screen opens.

3. Click the Create button. 

The New Persistence Profile screen opens.

4. In the Name box, type a name for this profile. In our example, we

type Tomcat-cookie.

5. From the Persistence Type list, select Cookie.

The configuration options for cookie persistence appear.

6. From the Cookie Method row, click the Custom box and then

select Cookie Hash.

7. In the Cookie Name box, type JSESSIONID.

8. Click the Finished button

Important

If your application only uses JSession cookie, it is safe to use the built-in

cookie persistence profile which yields the fastest persistence results.

If using persistence, it is a good idea to have a backup persistence method.

In this example, we use Source Address Affinity.

To create a Source Address Affinity persistence profile

1. On the Main tab, expand Local Traffic, and then click Profiles.

The HTTP Profiles screen opens.

2. On the Menu bar, click Persistence.

The Persistence Profiles screen opens.

3. Click the Create button. 

The New Persistence Profile screen opens.
