Parameters
webForPermissions
Type: Microsoft.SharePoint.SPWebThe SPWeb object that provides the access control list (ACL) for the site collection group security permissions.
updateCache
Type: System.BooleanA Boolean value specifying whether the taxonomy cache should be updated immediately. true if the cache should be immediately updated; otherwise false.

Remarks
The TaxonomySession object is the starting point for all operations involving objects from the taxonomy. It provides access to one or more TermStore objects, (for example, managed metadata connections), where the Microsoft.SharePoint.Taxonomy.Group, TermSet, and Microsoft.SharePoint.Taxonomy.Term objects reside.
Setting the updateCache parameter to true is equivalent to calling the UpdateCache() method, and causes the taxonomy cache to be updated immediately. This is normally unnecessary and may harm performance; it is mainly used immediately before performing a change, to reduce the likelihood of save conflict errors.
