Examples
A Hashing on the URL
In this example, URL hashing is enabled. If the host field does not exist, the specified length of
the URL is used to hash into the cache server as shown in Figure 71 - URL Hashing for
Application Redirection, page 476. If the host field exists, the specified length of both the host
field and the URL is used to hash into the cache server. The same URL request goes to the same
cache server:
— Client 1 request http://www.radware.com/sales/index.htmis directed to cache server 1.
— Client 2 request http://www.radware.com/sales/index.htmis directed to cache server 1.
— Client 3 request http://www.radware.com/sales/index.htm is directed to cache server 1.

B Hashing on the Host Header Field Only
In this example, URL hashing is disabled. If you use the host header field to calculate the hash
key, the same URL request goes to the same cache server:
— Client 1 request http://www.radware.com is directed to cache server 1.
— Client 2 request http://www.radware.com is directed to cache server 1.
— Client 3 request http://www.radware.com is directed to cache server 1.
C Hashing on the Source IP Address
In this example, URL hashing is disabled. Because the host header field does not exist in the
HTTP header, the source IP address is used as the hash key and requests from clients 1, 2, and
3 are directed to three different cache servers:
— Client 1 request http://www.radware.com is directed to cache server 1.
— Client 2 request http://www.radware.com is directed to cache server 2.
— Client 3 request http://www.radware.com is directed to cache server 3.
