1, first you want to make sure that you have an external network IP address. If you assign a local area network IP address, you need to go through a series of conversions to an extranet IP address, and then proceed to the following operation.2, get the external network IP address, the configuration of Tomcat Server.xml file. The following three places are mainly configured (the Tomcat version number used for this configuration is 7.0.30)1) 2)

2. Installing and setting up firewalls

The basic idea is how to make the CPU hyper-threading or multi-core more balanced and efficient use. We know that there is always a CPU dedicated to responding to the NIC interrupt requests. If the network request package is very large, A single CPU may not be able to handle the problem. Therefore, you need to activate multi-core or hyper-threading to distribute Nic interrupt requests to multiple CPUs for execution, so as to improve the overall
As we all know, Microsoft products always attract hackers, and IIS is no exception.
What is IIS
As one of the popular Web servers, IIS provides powerful Internet and Intranet services. Therefore, there are still many units that use IIS as Web server software. By default, these servers must allow public access to their resources. However, we found that many organizations spend far more time defending against attacks than maintaining and providing Web s

When creating a certificate, it expires one year after the creation date by default. Therefore, pay attention to the expiration time of the certificate creation. The following describes how to create a HOST_A_cert certificate on the "principal server ".

offline from the network to help ease security concerns. This is a good method for virtualized environments.
If the virtual machine can be detached from the environment of the Management Program, intruders will have the opportunity to access the management program that controls the virtual machine, thus avoiding the security control system specially designed to protect the virtual machine. Security issues in the virtual world are trying to get out of the control of virtual machines. Although no
point to modify the code, the following is a reference, the idea is to let the empty parameters of the case can both get the field, but also by pre-executionFor example, write the following styleIF ISNULL(@begtime,"')= "' OR ISNULL(@endtime,"')= "' BEGIN SELECT [C1] , [C2] , [C3] , [C4] fromTest1;--We have to get him to find the field, or the result set dataset won't be out of the field .

First, a brief introduction to the classification of agents:
Agent score: Level 1~level 55 grades;
Or it can be divided into 3 categories: ·
A. All anonymous agents don't change your request.
Fields, making the server side look like there's a real client browser accessing it. Of course, your real IP is hidden. The server's webmaster does not think you are using a proxy.
B. Ordinary anonymous agents can
After SQL server log transfer is configured, the SQL server log is very large because the backup database is large and the time is frequent. For example:
Because we already have log shipping monitoring, this backup information is basically useless to us. Is there any way to make the Information Department appear in the database error log? The answer is trace
Seda wrote n complex sandstorm, the idea of Seda itself is very simple. Using jdk1.5 to provide us with good thread support, it is a hundred lines.
Code To implement a Seda model.
3. Stax
Use Stax instead of Dom or sax. Streaming XML parsing consumes less memory and is faster.
Dom is very memory-consuming and cannot be considered in terms of performance. Sax is very huge and cool. It is slower than pull-type stream parser. Stax is the product of
We know that the direct use of ASP is not enough to restart the server, then we need to make a component to implement the function, ASP through this component calls the system API, and then according to different restart and shutdown mode to operate!
We know that the direct use of ASP is not enough to restart the server, then we need to

official offer method:
The operating system we use is all windows, and Microsoft offers us an official solution. In a network of Windows system builds, if an unauthorized DHCP server is built with a Windows system, we can filter the unauthorized DHCP server through the "domain" approach. By adding a legitimate DHCP server to the Active Directory (Active Directo
SQL Server Performance Tuning 3 Index MaintenancePreface
The previous article introduced how to improve database query performance by creating indexes, which is just the beginning. If you do not need proper maintenance in the future, the indexes you have previously created may even become a drag-and-drop attack and a helper for database performance degradation.Search for fragments
