HTTP Content Sticky Group Attributes
Table 7-2 HT TP Conte nt Sticky Group Attributes
Field Description
HTTP Content HTTP content may change over time with only a portion remaining constant
throughout a transaction between the client and a server.
Check the check box to configure the ACE to use the constant portion of
HTTP content to make persistent connections to a specific server. Clear the
check box to identify specific content for stickiness in the Offset, Length,
Begin Pattern, and End Pattern fields.
Offset (Bytes) Enter the number of bytes the virtual server is to ignore starting with the first
byte of the cookie. Valid entries are integers from 0 to 999. The default is 0
(zero), which indicates that the virtual server does not exclude any portion
of the cookie.
Length (Bytes) Enter the length of the portion of the cookie (starting with the byte after the
offset value) that the ACE is to use for sticking the client to the server. Valid
entries are integers from 1 to 1000.
