4Secure Bi-Directional Transfer (4BDT™)
4BDT™ is a bi-directional TCP proxy designed to be used in conjunction with two separate OPDS products. 4BDT™ allows ‘response’ data to be securely returned to an outbound TCP session. 4BDT™ is usually used in conjunction with 4XJS™ to securely filter the inbound and outbound traffic, typically HTTP request and response data.
4BDT™ is installed onboard the OPDS platform.
