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.

Specified by:

execute in interface Command

request - the original HTTP request

parameters - The parameters for this command

variables - The global variables for the parse

Returns:

a Reply with the output from the command
