Today, I saw such an interview on the Internet, which triggered a series of online knowledge searches and reviews ...... As we all know, http is a network application layer protocol, while TCP/IP is a network transport layer protocol. The two have different layers and there is no way to compare them.

You must have used the database import and export function in phpmyadmin to import and export a large number of data programs. However, in practical application, I found the following problems: 1. the size of the database exceeds a certain size. for example, if the size of 6 MB is used for export, the database can be correctly saved to the hard disk of the local machine, but cannot be imported! The reason

application Variableif (application["Name"]! = NULL)Label3.text = application["Name"]. ToString ();HttpContextYou can use HttpContext to get the values back from the Web page. These values are obtained by using the properties of the method. Since they are easy to write code and modify, using attributes is a good way. In your first page, create a property that returns the value of the TextBox.public string GetName{get {return txtname.text;}}We use Server.Transfer to send this control to a new pa

I need to use fiddler to capture Android APP data packets and Debug PHP programs. You need to debug the PHP program when the Android APP initiates a request to the server. To split the target, follow these steps: Debugging PHP using ECLIPSE + XDEBUG, while XDEBUG requires the get method to pass a parameter or set a COOKIE to trigger the breakpoint. I use the COOKIE method (I think this method is better)
