public java.util.Dictionary initVariables(SSIFrame ssiframe,

                                          java.util.Dictionary variables)

Description copied from class: CommandRegistry

Initialize execution variables. Called before any of the SSI commands in the documents are executed. This method augments or modifies the dictionary given as argument. If the variable dictionary is null, it may create a new one and return it. SSIFrame will always call this method with variables set to null. Its existence is mainly to facilitate the subclassing of an existing registry.

Specified by:

initVariables in class CommandRegistry

request - the HTTP request

variables - other variables previously defined

Returns:

the modified/augmented set of variables
