Rotten mud: understanding and application of iis host Header

This article was sponsored by 51cto.com and first launched in the dark world.

In the previous article "rotten mud: using IIS, Zblog, and SQLServer to build an ASP blog", we introduced the configuration of the iis host header. In this article, we will explain the application of the Host Header in depth.

We switch to the properties interface of the ilanni website, for example:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image001 "border =" 0 "alt =" clip_image001 "src =" http://www.bkjia.com/uploads/allimg/131227/1K12BS4-0.png "width =" 498 "height =" 479 "/>

Select "advanced" to go to the interface, as shown in:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image002 "border =" 0 "alt =" clip_image002 "src =" http://www.bkjia.com/uploads/allimg/131227/1K1262221-1.png "width =" 500 "height =" 469 "/>

On this page, we can see that the current host header is ilanni.com. We can access blogs in the form of http://ilanni.com, such:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image003 "border =" 0 "alt =" clip_image003 "src =" http://www.bkjia.com/uploads/allimg/131227/1K1261256-2.png "width =" 416 "height =" 304 "/>

But if we can access a blog in the form of http://www.ilanni.com?

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image004 "border =" 0 "alt =" clip_image004 "src =" http://www.bkjia.com/uploads/allimg/131227/1K12C3b-3.png "width =" 521 "height =" 495 "/>

We can see that we cannot access it now. Now we add the Host Header www.ilanni.com, for example:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image005 "border =" 0 "alt =" clip_image005 "src =" http://www.bkjia.com/uploads/allimg/131227/1K1264058-4.png "width =" 570 "height =" 505 "/> 650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image007 "border =" 0 "alt =" clip_image007 "src =" http://www.bkjia.com/uploads/allimg/131227/1K12C929-5.jpg "width =" 569 "height =" 462 "/>

Now we can see that both the form ilanni.com and www.ilanni.com can be accessed.

This is an access method. What if my current host header is a.com? For example:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image008 "border =" 0 "alt =" clip_image008 "src =" http://www.bkjia.com/uploads/allimg/131227/1K1261336-6.png "width =" 433 "height =" 314 "/>

The access result is as follows:

650) this. width = 650; "style =" background-image: none; margin: 0px; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image010 "border =" 0 "alt =" clip_image010 "src =" http://www.bkjia.com/uploads/allimg/131227/1K12B9E-7.jpg "width =" 580 "height =" 357 "/>

Obviously, a.com and ilanni.com are used to access the same website. This form of access applies. If a company or individual has multiple domain names, it is best to access the same website.

PS: All domain names involved in this article must be mapped in the hosts file. For example:

650) this. width = 650; "style =" background-image: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; "title =" clip_image011 "border =" 0 "alt =" clip_image011 "src =" http://www.bkjia.com/uploads/allimg/131227/1K12C5Y-8.png "width =" 497 "height =" 585 "/>
