In many other ways, they emulate transmissions associated with the TCP/IP protocol, allowing you to keep state if necessary and to track return information to the user to confirm HTTP requests. Effectively, it is like having the best of both worlds. Why Web Services Are Superior to Winsock and DCOM The following subsections discuss the history of Winsock and DCOM.

If your intentions were to navigate to an entirely new page, then this behavior was acceptable. If your intentions were simply to update a field in a table on an otherwise static page, then this behavior was costly. Running entire pages through IIS for processing takes time. If your Web application utilizes DCOM objects, then you can expect some latency. ASP pages are fundamentally scripted, so the code was never compiled until the page was processed through IIS.
