This rule extracts all the hidden form fields from an HTML page and stores them in the context so a subsequent request can use the hidden form field values. Each extracted hidden field will be stored in the context using the following naming convention: $HIDDEN<name>.<HiddenFieldName> where name is the Context Parameter Name set on the ExtractHiddenFields rule. When another ExtractHiddenFields rule uses the same Context Parameter Name, all existing hidden fields using that name will be removed from the context.

NoteNote

This rule is automatically inserted by the Web Test Recorder when it detects that hidden fields are being used. When requests to multiple windows or frames are recorded, the Web Test Recorder will automatically set the Context Parameter Names to different values when necessary. This will allow multiple sets of hidden fields to be in the context at the same time.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
