Remote scripting - enhances ASP interactivity and improves a big tool for ASP response
One. Summary.
Remote Scripting (Requirening RS) is a technology that Microsoft uses Java Applet to expand the ASP function. RS technology gives developers' ability to combine customers and servers on the same page.
In the dynamic web domain, in the past, VBScript, JavaScript handles the user interface in the client, and do some pre-process work before submission. If you interact with the server side, you must submit the entire Form within the server. The server-side receives the submitted data to do some processing, and then returns the processing result to the client.
If RS technology is used, the client program interacts with the server can bypass the process of submitting, directly call the server-side handler, and then get the return result is displayed on the client. For example, new users in a website When registering, you often need to fill in a registration form, which will contain information such as "User Name", "Password", fill in the completion "Submit" button, this user registration information is sent to the server, the server detects "user name" Duplicate, there is a prompt error, no newly registered a user. This way the user doesn't know if the user has existed in the process of the user, and it is necessary to wait until the entire form will be obtained. RS technology can search the server-side database when the user just fills in "Username", and gets the result of repetition, prompting the user to replace the user name, so that the entire registration is successful, reducing the time to return The interactivity of the program is also improved.
RS technology can improve the response speed of the ASP program (ASP running speed is not improved), because the normal method must submit the entire form (FORM), the form not only contains the data input data, but also the client address, user browser, Screen information, etc., multiple data, then wait for the server to return processing. The RS technology has bypassed the process of form submission, directly calling the program on the server, then returning the result, which although the server is handled this piece as before However, due to the process of removing the form, the response speed is improved. Typical applications such as search, refresh, etc.
