Parameters:

ba1 - the first byte array

off1 - where to start in the first array

ba2 - the second byte array

off2 - where to start in the second array

n - the length to compare up to

Returns:

true if both specified parts of the arrays are equal, false if they aren't .

                       throws ProtocolException,
                              ResourceException

Makes sure that checkContent() is called on _any_ HTTP method, so that the internal representation of commands is always consistent.

Overrides:

perform in class HTTPFrame

Parameters:

request - The HTTPRequest

Returns:

a ReplyInterface instance

Throws:

ProtocolException - If processing the request failed.

ResourceException - If this resource got a fatal error.
