Great point, I was thinking about 4.2, 4.5 is very different and new so the
jury is still out on that...

Check out this article on load balancing AAC servers. My experience getting
this working has not been good.

Also, if you are thinking of upgrading to AAC 4.5, check out the readme:
Support of Web Interface for Citrix Presentation Server 4.0 and 4.2
The following are known issues when Web Interface for Citrix Presentation
Server 4.0 or 4.2 are used in an environment that includes Access Gateway
Advanced Edition 4.5:
Cookies written during user sessions exceed cookie limit in Internet
Explorer
When users access an Access Platform site through the Access Interface using
Internet Explorer, the number of cookies written by the Advanced Access
Control server exceeds Internet Explorer's cookie limit of 20 per unique
domain. When this happens, Internet Explorer discards the oldest cookies so
that newer ones can be written. This results in a loss of session state
during a typical user session and, consequently, a loss of functionality.
This issue also occurs when the Advanced Access Control server is configured
to display multiple Access Platform sites. This issue does not occur when
using Web Interface for Citrix Presentation Server 4.5 to provide access to
published applications through the Access Interface.
Users are unable to set connection preferences from the Access Interface
When users log on to an Access Platform site through the Access Interface,
they cannot customize the connection preferences for the site. For example,
when users select options from the Connection Preferences page and click OK,
the selections are not saved. This occurs because Advanced Access Control
causes the cookie set by Web Interface to expire. This issue does not occur
when using Web Interface for Citrix Presentation Server 4.5 to provide
access to published applications through the Access Interface.
Sessions are not shared when users access published applications
When users launch published applications through Advanced Access Control or
an Access Platform site displayed in the Access Interface, the sessions that
are created with each access method are not shared. For example, when a user
accesses a published application using file type association or Workspace
Control, a session is created. When the user disconnects from the
application and then reconnects using an Access Platform site displayed in
the Access Interface, the session is not used. Instead, a new session is
created. While the user's experience remains unaffected, administrators
might notice the server running Citrix Presentation Server experiences some
decrease in performance. This decrease varies depending on the usage of
published applications through Advanced Access Control. This issue does not
occur when using Web Interface for Citrix Presentation Server 4.5 to provide
access to published applications through the Access Interface.
Installation of Web Interface for Citrix Presentation Server 4.2 on Advanced
Access Control server is not supported.
Installing Web Interface for Citrix Presentation Server 4.2 on the same
server hosting Version 4.5 of Advanced Access Control is not a supported
installation scenario. To use Version 4.5 of Advanced Access Control in an
environment that includes Web Interface for Citrix Presentation Server 4.2,
Advanced Access Control must be installed on a separate server. This issue
does not occur when installing Web Interface for Citrix Presentation Server
4.5 on a server hosting Version 4.5 of Advanced Access Control.

It is no problem to combine them, it saves hardware but does create a single
point of failure. However, if you have multiple servers doing this, you are
covered there..

Subject: [THIN] AAC and WI on the same box?
How many folks who are running the CAG/AAC are also using the AAC boxes for
WI access?
I am re-architecting our citrix environment to include the CAG/AAC in an HA
scenario. All components will be at the latest versions. I know we will
need a group of AAC servers, and a group of WIs at each site. Is there any
disadvantages in combining the AACs and WIs, besides having to scale out a
bit to cover the load?? Still, combining them should still require fewer
machines then if I kept them separate. The WIs will be serving up the
config.xml for internal PNA and some web access as well as the AAC sites.
I'm thinking if I can keep the web boxes identical that it will make it a
bit easier to support.
Thanks for your input,
