Optimize Citrix Web Client for WAN caching

Ok, so this like really sucks because it's a catch 22. Citrix web client by default disables caching of everything except for 8MB of RAM cache.

The fix is to go into your default.ica files and add these lines;

[WFClient]
PersistentCacheEnabled=On
PersistentCacheMinBitmap=2048
PersistentCacheSize=64424508
PersistentCachePath=%appdata%
Compress=On
MaximumCompression=On
OutBufCountHost=118
OutBufCountClient=118
OutBufLength=512
OutBufCountHost2=118
OutBufCountClient2=118
MouseTimer=200
KeyboardTimer=50

[Application]
PersistentCacheEnabled=On
PersistentCacheMinBitmap=2048
PersistentCacheSize=64424508
MaximumCompression=On
PersistentCachePath=%appdata%
Compress=On



The problem is that persistentcachepath does not allow variables such as %userprofile% until the 11.2 client, and users do not have access to the default paths.



If you don't specify PersistentPathCache, then PersistentCache is disabled.  If you stick the cache in c:\temp and grant everyone full rights, it's a security issue.



The 11.2 client also removes PNAgent and program neighborhood. So it's a catch22. If you upgrade to 11.2, you can't connect to old farms.   If you don't upgrade then Webclient bitmap caching doesn't work right.



If you have bandwidth detection enabled, then the ICA settings will be different. In our setup, we have only low bandwidth users. The low bandwidth ica is not combined with default.ica. Only settings in the specific ICA are used, they are not merged.
