Chapter 5 Configuring Virtual Servers

Configuring Virtual Servers

Enable Insert This option appears for sticky type HTTP Cookie.

Check this check box if the virtual server is to insert a cookie in the Set-Cookie header of the

response from the server to the client. This option is useful when you want to use a session cookie

for persistence but the server is not currently setting the appropriate cookie. When selected, the

virtual server selects a cookie value that identifies the original server from which the client

received a response. For subsequent connections of the same transaction, the client uses the cookie

to stick to the same server.

Clear this check box to disable cookie insertion.

Browser Expire This option appears for sticky type HTTP Cookie and you select Enable Insert.

Check this check box to allow the client's browser to expire a cookie when the session ends.

Clear this check box to disable browser expire.

Offset (Bytes) This option appears for sticky types HTTP Cookie and HTTP Header.

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) This option appears for sticky types HTTP Cookie and HTTP Header.

Enter the length of the portion of the cookie (starting with the byte after the offset value) that the

ACE appliance is to use for sticking the client to the server. Valid entries are integers from 1 to

1000.

Secondary Name This option appears for sticky type HTTP Cookie.

Enter an alternate cookie name that is to appear in the URL string of the Web page on the server.

The virtual server uses this cookie to maintain a sticky connection between a client and a server

and adds a secondary entry in the sticky table. Valid entries are unquoted text strings with no spaces

and a maximum of 64 characters.

Header Name This option appears for sticky type HTTP Header.

Select the HTTP header to use for sticking client connections.

Select the netmask to apply to the source IPv4 address, destination IPv4 address, or both.

Prefix Length This field appears for sticky type V6 Prefix. This field is optional for the sticky type IP Netmask.

Enter the prefix length to apply to the source IPv6 address, destination IPv6 address, or both.

address, or both:
