ASP Reading Notes (2)-built-in objects

1. Request object
1. Use the get method to submit form data and request. querystring ("") to process a single table page. The parameter is the name attribute value of the form element.
2. Use the POST method to submit the form data and process the single page of the table. Request. Form (""); the parameter is the name attribute value of the form element.
3. Obtain the size of data bytes received by the client, and use request. totalbytes
4. How to read data in binary code mode. The request object provides a binaryread method to read data submitted by the client using the POST method in binary code mode. The customer outputs data using a binarywrite method.
For example: dim arrays (1000) arrays (1) = request. binayread (request. totalbytes)
Response. binarywrite (arrays (1 ))

Current file name: request. servervariables ("path_info ")
Client IP: request. severvariables ("remote_addr ")
Host Name: request. servervariables ("SERVER_NAME ")
