Abstract: Remote access service is provided between two or more computers on a network to facilitate a variety of activities, including desktop sharing, web-meetings, and web-conferences. A first computer sends its connection information to a server. The server stores the connection information for the first computer. A second computer may make a request to the server to remotely access the first computer. The server sends to the second computer the connection information it has stored for the first computer. The second computer uses the connection information for the first computer to send to the first computer connection information for the second computer via direct network connection. From this point on, the first computer and the second computer exchange data for remote access via a direct network connection, independently of the server.

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.
