Method Detail

execute

public Reply execute(SSIFrame ssiframe,
                     Request request,
                     ArrayDictionary parameters,
                     java.util.Dictionary variables)

Description copied from interface: Command

Executes this command. Might modify variables. Must not modify the parameters.

It may handle conditional requests, except that if it replies with a status of HTTP.NOT_MODIFIED, it must still reply with a content (the same content that it would have returned for an inconditional request). This is because further SSI commands down the line may decide thay they have been modified, and then a content must be emitted by SSIFrame.

variables - The global variables for the parse

Returns:

a Reply with the output from the command
