Abstract
Apparatus and methods are provided that prevent cross-site request forgery at one or more web servers. A proxy dynamically monitors web server responses to client requests for content having a selected characteristic, adds a hidden token to content identified as having the selected characteristic prior to serving the content to a requesting client, and stores a copy of the hidden token for later verification that client request content sent to a web server is authentic. The proxy monitors client request content sent to the one or more web servers for a selected characteristic, and allows client request content having the selected characteristic to be processed by a web server application only if the client request content includes a token previously provided by the proxy and only if the token has a value matching a stored token value for the respective client.
