ABSTRACT:
Systems and methods for emulating a persistent connection using, for example, hypertext transfer protocol (HTTP) transactions over a transmission control protocol (TCP) connection. The persistent connection is maintained by adjusting content length values in HTTP requests and/or HTTP responses. The content length values are associated with methods such as GET and POST actions. The values of the content length are determined in order to keep the connection open for an estimated period of time. Prior to expiration of the time period, a new HTTP request or response is sent in order to keep the connection open for an additional period. If the connection is prematurely closed, the estimated time period is reduced and/or the content length value can be increased. A network conditions detector determines characteristics of the network such as bandwidth for use when determining the estimated time period and the content length value.
