First, introduce the data table structure involved, four fields:
The code is as follows:

1, the client sends the request to the server side regularly. The implementation method is after the user login, insert uid,session_id,login_time a record, and then set a timer on the client JS, such as sending a request to the server every 10 minutes to achieve the purpose of updating the
following pseudo code:
f0={}
f0["ddddd"] = f1[' DDDD ']
f0[' upass '] = calcMD5 (pid + f1[' UPass '] + calg) + calg + pid;
f0["R1"] = SS
f0["R2"] = 1
f0["para"] =
f0["0MKKey"] = 123456
where SS, PID, Calg are constants, f1[' DDDD ', f1[' UPass ', respectively, are user-entered username and password strings
The key is the CALCMD5 algorithm.
From the function names and functions themselves, this function is an implementation of MD5. However, there are some problems in the pro

powerful but paid.The basic idea for implementing this function with scripts is as follows:1. When a user logs on, check all logon records of the current user in the database. If the account information is not found, Allow logon and record the Logon account, client location, and time;2. When another user logs on with the same account, the same check is performed. Because there are logged on information records, it indicates that the current Logon account is a duplicate logon, and login is prohi

The following example demonstrates how to use both the authenticate () and login () functions in a view:

If you can determine whether a user is logged in, you can dynamically customize the view with Flash, JavaScript, DHTML, or any other browser-based code. You may find that a logged-on user can log out of the system or view its profile, and the logged out user can sign up or sign in again.Figure 1. Login and logout

When the user returns to the home page, they will notice that the LoginStatus is removed, that they have passed the authentication, and that a logout link is displayed. Clicking on the login link will cause the user authentication ticket (ticket) to be cleared and display the login link. At this point, users can click on the login link, because they have created a user a
groups, the first group is for the login page, the second group is the logout page, The third group is the filtering of any request, and the control of the permissions is also implemented in this set of filter chains. My understanding is that mastering the role of the third group of filter chain, basic to Spring-security has a basic use of the master.
Here's a detailed look at the filter chain:

The ihttphandler interface mainly uses the custom HTTP handler. For example, when a user accesses a page, the programmer can re-process whether to let the user see the page by implementing the "processrequest" method of this interface.
Custom processing programs can be written in any language that complies with CLS specifications. After a custom processing program is compiled, your requests are not responded to through ASP. NET pages, but through the "processrequ

After CAS is single-point logout, it will jump to its own logout interface by default (this is based on the deployed CAS-Server. For details, see the previous article), such:

["upass"] = calcMD5(pid + f1['upass'] + calg) + calg + pid; f0["R1"] = ss f0["R2"] = 1 f0["para"] = 00 f0["0MKKey"] = 123456
Ss, pid, and calg are constants. f1 ['ddddd'] and f1 ['upload'] are user names and password strings respectively.
The key lies in the calender 5 algorithm.
From the function name and function itself, this function is an implementation of MD5. However, some problems occur during the JavaScript code porting process: the Migration Operations of js and python are different.
