-- Exhibit --

Refer to the exhibits.

An LTM Specialist is troubleshooting an issue with one of the virtual servers on an LTM device, and all requests are receiving errors. Testing directly against the server generates no errors. The LTM Specialist has captured the request and response on both client and server sides of the LTM device.

What should the LTM Specialist do to fix this issue?

A failover event is recorded in the log messages:

What is the cause of the failover?

The LTM Specialist is writing a custom HTTP monitor for a web application and has viewed the content by accessing the site directly via their browser. The monitor continually fails. The monitor configuration is:

ltm monitor http /Common/exampleComMonitor {

defaults-from /Common/http

destination *:*

interval 5

recv "Recent Searches"

send "GET /app/feed/current\?uid=20145 HTTP/1.1\\r\\nHost: gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"

time-until-up 0

timeout 16

}

A trace shows the following request and response:

Request:

GET /app/feed/current?uid=20145 HTTP/1.1

Host

Accept-Encoding gzip, deflate

Connection: close

Response:
