Receiving Responses SIP Servlets Versus HTTP Servlets
1.2.3 Proxy Functions
Another function that is different from the HTTP protocol is forking. Forking is a process of proxying one request to multiple servers simultaneously or sequentially Overview of SIP Servlet Application Development 1-5 and used when multiple terminals operators are associated with one telephone number such as in a call center. Figure 1–4 Proxy Forking SIP Servlet provides a utility to proxy SIP requests for applications that have proxy functions.1.2.4 Message Body
As shown in Figure 1–5 , the structure of SIP messages is the same as HTTP. Figure 1–5 SIP Message Example HTTP is basically a protocol to transfer HTML files and images. Contents to be transferred are stored in the message body. HTTP Servlet defines stream manipulation-based API to enable sending and receiving massive contents.1.2.4.1 Servlet Request
