Method and infrastructure for accessing remote applications through a secure firewall

A computer program product comprising a computer readable hardware program storage medium, the computer readable hardware program storage medium including a computer readable program comprising program instructions to:

• send, from a first hardware system that executes an application, a first HTTP request to a second hardware system via an open network, the first hardware system being located behind a first secure firewall, the second hardware system being located behind a second secure firewall;
• receive, at the first hardware system, an HTTP response having an application request from the second hardware system;
• process, at the first hardware system, the application request received from the second hardware system to generate an application response that includes an allowance of access that is determined by the first hardware system, the allowance of access providing secure remote access of the application to the second hardware system without having to open an additional port through the first secure firewall;
• and
• send, from the first hardware system, a second HTTP request to the second hardware system, the second HTTP request including the application response.

A method comprising:

• receiving, from a first hardware system that executes an application at a second hardware system, a first HTTP request via an open network, the first hardware system being located behind a first secure firewall, the second hardware system being located behind a second secure firewall;
• sending, from the second hardware system, an HTTP response having an application request to the first hardware system so that the application request is processed at the first hardware system to generate an application response that includes an allowance of access that is determined by the first hardware system, the allowance of access providing secure remote access of the application to the second hardware system without having to open an additional port through the first secure firewall;
• and
• receiving, from the first hardware system at the second hardware system, a second HTTP request, the second HTTP request including the application response.

A hardware system located behing a secure firewall comprising:

• means for executing an application;
• means for sending a first HTTP request to an additional hardware system via an open network, the additional hardware system being located behind a second secure firewall;
• means for receiving an HTTP response having an application request from the additional hardware system;
• means for processing the application request received from the additional hardware system to generate an application response that includes an allowance of access and determining an allowance of access, the allowance of access providing secure remote access of the application to the additional hardware system without having to open an additional port through the secure firewall;
• and
• means for sending a second HTTP request to the additional hardware system, the additional HTTP request including the application response.

A hardware system located behind a secure firewall comprising:

• means for receiving, from an additional hardware system that executes an application at the additional hardware system, a first HTTP request via an open network, the additional hardware system being located behind an additional secure firewall;
• means for sending an HTTP response having an application request to the additional hardware system so that the application request is processed at the additional hardware system to generate an application response that includes an allowance of access that is determined by the additional hardware system, the allowance of access providing secure remote access of the application without having to open an additional port through the additional secure firewall;
• and
• means for receiving, from the additional hardware system, a second HTTP request, the second HTTP request including the application response.
