Accelerating multiple web servers hosting multiple websites in .NET Include QR Code 2d barcode in .NET Accelerating multiple web servers hosting multiple websites

9. generate, create qrcode none with .net projects Microsoft .NET Accelerating multiple web servers hosting multiple websites In this examp le, we have example.com and its sub-domains hosted on 192.0.

2.25, example.net and its sub-domains hosted on 192.

0.2.26, and example.

org and its sub-domains hosted on 192.0.2.

27. We have a Squid server installed on a different machine with a public IP address and all the domains (example.com, example.

net, example.org, and their sub-domains) point to the public IP address of the Squid server. The following is an example of such a configuration:.

http_port 80 .net framework qr bidimensional barcode accel vhost defaultsite=www.example.

com ignore-cc cache_peer 192.0.2.

25 parent 80 0 no-query originserver name=server1 cache_peer 192.0.2.

26 parent 80 0 no-query originserver name=server2 cache_peer 192.0.2.

27 parent 80 0 no-query originserver name=server3 cache_peer_domain server1 .example.com cache_peer_domain server2 .

example.net cache_peer_domain server3 .example.

org. Note that we can"t use the round-robin option with the cache_peer directive here because different web servers are hosting different domains. We have also restricted request forwarding using the cache_peer_domain directive so that we contact only the relevant web server for forwarding the requests..

Have a go hero set up a Squid proxy server in reverse proxy mode Try to set up a Squid proxy server in reverse proxy mode as a server accelerator for your website on the same server as web server.. Pop quiz 1. When the i gnore-cc option is used while specifying http_port as follows:. http_port 80 accel vhost ignore-cc What will hap pen when a client clicks on the reload button in the browser a. Squid will not receive the Cache-Control HTTP headers. b.

The ignore-cc option doesn"t affect client requests. c. Squid will ignore the Cache-Control HTTP header from the request.

d. The backend web server will ignore the Cache-Control HTTP header..

[ 237 ]. Squid in Reverse Proxy Mode 2. Consider t visual .net QR-Code he following configuration:.

2.25. Summary. In this chapt Denso QR Bar Code for .NET er, we learned about Squid"s reverse proxy mode, which can be used to share the load of a very busy web server or a cluster of web servers. We also learned about the various configuration options to configure Squid in reverse proxy mode.

Specifically, we covered: What is a web server accelerator and how does Squid fit in this model. Configuring Squid to accept HTTP and HTTPS requests from clients on behalf of our web servers. Adding backend web servers to Squid so that it can forward requests to origin servers appropriately.

We also saw a few configuration examples in which we tried to accelerate various web servers hosting different websites. In the next chapter, we"ll learn about configuring Squid in intercept mode..

[ 23 ]. Squid in Intercept Mode In previous c hapters, we have learned about using Squid in the forward proxy and accelerator or reverse proxy modes. In this chapter, we are going to learn about configuring Squid in the intercept (or transparent) mode. We"ll learn about Squid"s behavior in the intercept mode and also the basic configuration required for achieving interception caching.

. In this chapt Visual Studio .NET QRCode er, we shall discuss:. Interception caching Advantages of running Squid in the intercept mode Problems with the intercept mode Diverting HTTP traffic to Squid Implementing interception caching. So let"s get started... Interception caching When the requ QR-Code for .NET ests from clients are intercepted by a proxy server or are redirected to one or more proxy servers, without configuring the HTTP clients on the client machines or without the knowledge of clients, it"s known as interception proxying. As proxying is mostly accompanied by caching, it"s known as interception caching.

Interception caching is also known by several other names, such as, transparent caching, cache redirection, and so on. Squid can be configured to intercept requests from clients so that we can leverage the benefits of caching without explicitly configuring each one of our clients..
