x11 forwarding

one, the way to call We know that the statements in the servlet that call forward and redirect are as follows:Request.getrequestdispatcher ("new.jsp"). Forward (request, response);//Forwarding to new.jspResponse.sendredirect ("new.jsp");//Redirect to new.jspIn the JSP page you will also see the following way to implement forwarding:Of course, you can also implement redirects in the JSP page:Two, the essential difference explanation oneIn a word,

Sevlet response There is a way to redirect us to introduce you first.The Sendredirect (String Local) method of a 1.HttpServletResponse object is called a redirect. If the location address is preceded by a"/" means a request is made relative to the root of the servlet container, i.e. http://localhost:8080, if the location address money does not add "/", then the address is found relative to the URL of the current request.The forward (request, response) of 2.RequestDispatcher is called forward

a Cisco Professional-level device uses a large number of ASIC chips to forward packets. In fact, it uses a hardware cache mechanism. If these hardware can also be inserted into the gateway running Linux, the network forwarding performance of Linux will inevitably be greatly improved. However, hardware insertion is very simple. How can we make the software work with the hardware? We know that the combination of hardware and no software is a pile of wa

Theoretically, as long as the computer connected to the network is accessible, it is difficult to implement it due to technical level or other reasons. For example, a computer in the LAN only opens Web Services, this service is only available for Intranet users, but there is no direct access for Internet users. Therefore, to allow Internet users to access system services in the LAN, port ing and other operations must be performed. Port ing is often used when intruding into the Intranet. It is ve

Implementation of domain name-based layer-7 Forwarding (NAT + reverse proxy) and layer-7 nat In the company's actual office network, because there is only one outbound IP address, port ing is required to provide external services. If multiple services are to be opened to the outside world, this can only be distinguished by ing different ports, which is very painful in the actual use process (difficult to remember, the one-to-one correspondence is not

First: redirection is two requests and two responses. Request forwarding is a one-time request responsePopular speaking:Redirect: When you visit a page, it will return a new address to you, and then the browser will revisit the new page via the new address. The new page returns the result of the executionRequest forwarding: When a browser accesses a resource, the resource automatically accesses another reso

The balance is a TCP proxy software with load balancing and failover capabilities. Support IPV6 address monitoring and forwarding, support RR polling and IP hash.Some functions can be substituted for iptables, such as 80 port forwarding from local to 8080:Iptables is written in this way:Iptables-t nat-a prerouting-d 192.168.1.1-p tcp--dport 80-j DNAT--to 192.168.1.1:8080Balance only need this:Balance localh

Php code for Phpbean route forwarding Step 1: Getting started How can I use phpbean for route forwarding? The following is a simple example. First, index. php is a single entry to the program, mainly for routing and forwarding. The program code of Index. php is as follows: Include ('Startup. php'); // load the startup file Try { $ Router = new Phpbean_Router ()

executes a target, however, Netfilter can do more. I have heard of network accelerators for a long time, but I have always felt that optimization of some algorithms by software is definitely impossible to increase the performance statistics by an order of magnitude. I must have some hardware help, even a Cisco professional-level device uses a large number of ASIC chips to forward packets. In fact, it uses a hardware cache mechanism. If these hardware can also be inserted into the Gateway runnin

Basic idea: enable IP forwarding and set iptables rules. 2. 1. enable IP forwarding in either of the following ways: echo quot; 1 quot; gt;/proc/sys/net/ipv4/ip_forward fixed: modify/etc/sysctl. conf to cancel the annotation of this line: net. ipv4.ip _ forward1 and then immediately generate... basic idea: enable IP forwarding and set iptables rules. 2. 1.

Some mainstream blog publishing tools or websites have the mail publishing function. You can publish the Blog content by sending emails to an established address. In combination with the above two and automatic Email Forwarding, you can use a blog as the main function to synchronously update the remaining blogs. The following describes the detailed practices. Initial Conditions: email, RSS, and blog First, you need to have an email address. Here

Currently, openssh is widely used in linux.Ssh-related options: -V Show version:Ssh-V OpenSSH_6.6.1p1 Ubuntu-2ubuntu2, OpenSSL 1.0.1f 6 Jan 2014 -F Enter the password and enter the background mode (Requests ssh to go to background just before command execution .) -N Do not execute a remote command. This is useful for just for warding ports (protocol version 2 only ).) -D Socket5 proxy (Specifies a local "dynamic" application-level port forwa
