It is very necessary to compress the header of a webpage when the page size is large. This will significantly reduce the page size and increase the speed at which the webpage is downloaded from the server to the client, here is a test I did:
When Header Compression is not used:
After header compression is used:
We can see that the

Recently configured the server, found that setting up IIS needs to add hundreds of host header domain names, I quickly thought of the way to bulk add the host header: Export the IIS station configuration to an XML, then edit all the host headers into the XML, and then return to the IIS6 to overwrite the original site, so that the bulk of the host header is added.

In the previous section, we have a general understanding of the role of each part of the PE file. From this section, we will further explain each part of the PE file, of course, don't forget the two questions I raised in the previous section.
1. Dos MZ header and Dos Stub:
All PE files (or even 32-bit DLLs) must start with a simple dos MZ header. We are usually not very interested in this structure. With it
compilation process, but in the Link process, because the target code contains two fully-local X, there will be a link error: X redefinition.
Different programmers may write different modules. How can they avoid this situation?Avoid duplicate namespace names.
The Google programming specification encourages the use of an anonymous space:
// Source1.ccNamespace {Int X;
}
// Source2.cc
Namespace {
Int X;
}
Okay, now there is no link error because two X names are not duplicated. Of course, for this
it was actually a local persistence (which is my goal). Then someone said why I didn't use static, well, it seems that there is no difference between the two things at first glance.

In this case, a problem occurs. In the template, non-type parameters must have external links. Otherwise, compilation fails. For examp
