You can check whether the cookie contains a value such as id in the HTTP header. this value must be sent to the server each time a request is sent. The idea is still incomplete

additional information that cannot be placed in the status line. These fields mainly describe the server information and Request-URI information. The Response Header includes Age, Location, Proxy-Authenticate, Public, Retry-After, Server, Vary, Warning, and WWW-Authenticate. The expansion of the Response Header domain requires both parties to support the communication. If an unsupported Response Header dom

However, the server needs to write code and configure the config file to authenticate the user's identity. The specific authentication method is described in the following server settings. SendPlainText is a password transmitted in plaintext, if this method is used, it is

1 def index (): 2 print ("Welcome to the Index page") 3 Def Home (): 4 print ("Welcome to the Home page") 5 def BBS (): 6
If we want to add validation to the home page and BBS page now, obviously it is not feasible to change the source code now. This time we can use the adorner, as follows:

want to access through tokens or cookies. You can apply both Cookie and token authentication filters to these common methods of action, and there is always a filter that can successfully authenticate. This control is the most valuable authentication filter that can be pushed up to the table. When precise control of authentication is required, it is a good practice to resolve authentication-related issues through an authentication filter and to resolv

Location of SSL SSL is between the application layer and the TCP layer. The application layer data is no longer passed directly to the transport layer, but is passed to the SSL layer, which encrypts the data received from the application layer and adds i

The most complex protocol in SSL is the handshake protocol. This protocol allows the server and client to authenticate
at the following example: "' Gotype temporary Interface {temporary () bool}//IsTemporary returns True if Err is Temporary.func istemporary (E RR error) bool {te, OK: = Err. ( Temporary) return OK te.

If the error does not implement the temporary interface, then there is no temporary method, then the error is not temporary. If temporary is implemented incorrectly, then the caller can consider re

The next time the user tries to log in, the DC obtains the user's universal group membership information from the local cache without needing to link to the GC in the other site for information. Universal group membership information that is cached in the DC is refreshed by default 8 hours, and when the cache information is refreshed, the DC sends a universal group membership acknowledgment request to the specified GC. You can en

The httpservletrequest class includes both the getattribute () method and the getparameter () method. The two methods have the following differences:
(1) The httpservletrequest class has the setattribute () method instead of the setparameter () method.
(2) When two Web components are linked, the linked component obtains
