Session-server affinity for clients that lack session identifiers

摘要

The disclosed embodiments provide a system that facilitates interaction between a client and a web application. During operation, the system identifies a request that lacks a session identifier from the client to the web application. Next, the system obtains a client identifier associated with the client from the request. If a cached session identifier is found for the client identifier, the system adds the cached session identifier to the request. Finally, the system forwards the request to the web application.

1. A computer-implemented method for facilitating interaction between a client and a web application via an intermediary device, comprising:
receiving, at a device, a request from a client, wherein the request is directed to a web application executing on a plurality of servers, wherein the request lacks a session identifier, and wherein the client lacks the ability to provide session identifiers; obtaining a client identifier associated with the client from a Uniform Resource Locator (URL) associated the request; querying a cache with the client identifier to determine if a session identifier associated with the client identifier exists in the cache; if so, adding the session identifier to the request, wherein the device maintains the session identifier on behalf of the client, and wherein the session identifier is a separate identifier from the client identifier; forwarding the request to the web application.
