Method and Infrastructure for Accessing Remote Applications

An infrastructure for accessing a remote application running on a system A by a system B, wherein system A and system B are connected to an open network and are each located behind a firewall, the infrastructure comprising:

• means for sending HTTP requests from system A to system B via the open network;
• means for receiving HTTP responses from system B top system A via the open network;
• means for processing HTTP responses from system B to extract application requests and to forward the application requests to system A;
• and
• means for generating HTTP requests comprising application responses generated by system A.

An infrastructure for accessing a remote application running on a system A by a system B, wherein system A and system B are connected to an open network and are each located behind a firewall, the infrastructure comprising:

• means for receiving HTTP requests from system A to system B via the open network;
• means for sending HTTP responses from system B to system A via the open network;
• means for listening for application requests from system B concerning applications running on system A;
• means for blocking HTTP requests from system A to system B till an appropriate application request is available at system B;
• means for generating HTTP responses comprising application requests from system B;
• and
• means for processing HTTP requests received from system A to extract application responses and to forward the application responses to system B.

A computer program product comprising a computer readable medium, the computer readable medium including a computer readable program for accessing a remote application running on a system A by a system B, system A and system B each being connected to an open network and located behind a firewall, the computer readable program comprising program instructions for:

• system A sending a first HTTP request to system B via the open network;
• blocking the first HTTP request from system A till an appropriate request is available at system B for transfer to system A;
• system B sending an HTTP response to system A via the open network, the HTTP response comprising the application request;
• system A processing the application request from system B to generate an application response;
• system A sending a second HTTP request to system B via the open network, the second HTTP request comprising the application response;
• and
• blocking the second HTTP request from system A till another application request is available at system B for transfer to system A.
