System and method for enabling application server request failover

A system comprising:

• a client computer including a CPU and memory;
• a requesting thread stored in the memory of the client computer, wherein the requesting thread is operable to send a request to a first application server computer;
• a first application server computer including a CPU and memory, wherein the first application server is operable to receive the request, process the request, and return request results to the requesting thread;
• a second application server computer including a CPU and memory;
• and
• a network connecting the client computer to the first and second application server computers;
• wherein the requesting thread is executable to send a poll message to the first application server, wherein the poll message comprises information identifying the request, wherein the application server is operable to receive the poll message and respond by returning a status of the request to the requesting thread;
• wherein the requesting thread is further executable to determine whether a response to the poll message is received from the first application server;
• and
• wherein, if no response to the poll message is received, the requesting thread is further executable to send the request to the second application server and to cause the client computer not to send future requests to the first application server.

A memory medium comprising program instructions executable to implement:

• a requesting thread running in a client computer sending a request to an application server, wherein the application server is operable to receive the request, process the request, and return request results to the requesting thread;
• the requesting thread sending a poll message to the first application server, wherein the poll message comprises information identifying the request, wherein the application server is operable to receive the poll message and respond by returning a status of the request to the requesting thread;
• the requesting thread determining whether a response to the poll message is received from the first application server;
• and
• if no response to the poll message is received, the requesting thread sending the request to the second application server and causing the client computer not to send future requests to the first application server.
