Systems and methods for management of common application firewall session data in a multiple core system

A system for efficiently processing by an intermediary device strings in web pages across a plurality of user sessions, the system comprising:

• a device intermediary to a plurality of clients and a server, receiving web pages communicated by the server via a plurality of user sessions to the plurality of clients;
• one or more allocation arenas of the device for storing and sharing strings across user sessions;
• an application firewall module of the device identifying a plurality of strings in forms and uniform resource locators (URLs) of web pages and storing each string of the plurality of strings to the one or more allocation arenas, each string indexed using a hash key generated from each string,
• wherein the application firewall module recognizes that a received string transmitted from a web page of a session of a user is eligible to be shared among the plurality of user sessions and determines via a hash generated from the received string that a copy of the received string is stored in an allocation arena of the one or more allocation arenas;
• and
• wherein the application firewall module performs one or more security checks on the received web page using the copy of the received string from the allocation arena in place of the received string from the web page of the session of the user.
