Let's say the version of a file comes back as "1.1.4322"

variable4 = "1.1.4322"
variable3 = "1.1"

_lowerCasedClientScriptPathWithTrailingSlashV10 = "/aspnet_client/system_web/1_1_4322/

_lowerCasedClientScriptPathWithTrailingSlashV11 = "/aspnet_client/system_web/1_1/"

Hi sigme -
Please post this question on the ASP.NET forums ( http://forums.asp.net/)-- they should be better at helping you with cassini.

Thanks,
