In IIS 7.5, HTML supports the include function like SHTML (add module mapping)

When I first started, I found a lot of errors. In fact, it is very simple. Just refer to the original settings of shtm.

Prerequisites:

Installation of ServerSideIncludeModule:

When installing IIS, select the service ("Include files on the server", option), as follows:

1: Processing Mapper

Add module mapping request path *.html Module select ServerSideIncludeModule, name fill in: SSINC-html

2: Restart IIS

Enter iisreset /restart in cmd

The detailed steps are as follows

1. First find the website you want to modify, not the folder, then find the handler mapping on the right and double-click to enter

2. Find the following three

These three are stm, shtm, and shtml. They all have the same effect, but the suffixes are different. We can open them and take a look.

3. We use *.shtm to open it, and now we understand that it is implemented through module mapping , which makes it convenient for us to add later. Other .do files can be executed just like php. They are all the same. Just refer to the original mapping method.

4. We add a copy

Here, *.html supports shtm. You can see the added module mapping on the right.

5. The parameters are as follows

*.html

Select ServerSideIncludeModule from the drop-down

6. You can write a name that is easy for you to recognize.

7. Similarly, we can set *.htm in the same way

Let me share with you the usage of shtm

shtml is a file used for SSI technology. That is Server Side Include--SSI server-side include directive. Some Web Servers have SSI functions. shtml files will be treated specially. First scan the shtml file to see if there are any special SSI instructions. If there is, the SSI instructions are interpreted according to the Web Server setting rules. After the explanation, it is transferred to the client together with the general HTML.

1. Config command

The Config command is mainly used to modify the default settings of SSI. in:
Errmsg: Set the default error message. In order to return the error message set by the user normally, the Errmsg parameter must be placed before other SSI commands in the HTML file, otherwise the client can only display the default error message instead of the custom message set by the user.

Timefmt: Defines the format used for dates and times. The timefmt parameter must be used before the echo command.



The result is:

Wednesday, April 12, 2019

Perhaps users are unfamiliar with the %A %B %d used in the above example. Below we summarize some of the more commonly used date and time formats in SSI in the form of a table.

Sizefmt : Determines whether file sizes are expressed in bytes, kilobytes, or megabytes. If bytes are specified, the value is "bytes"; abbreviations for kilobytes and megabytes may be used. Likewise, the sizefmt parameter must be placed before the fsize command in order to be used.

2. Include command

The Include command can insert text or images from other documents into the currently parsed document, which is the key to the entire SSI. With the Include command, you can update your entire site instantly by just changing one file!

The Include command has two different parameters:
Virtual: Gives a virtual path to a document on the server. For example:

File: Give a path relative to the current directory. You cannot use "../" or an absolute path. For example:

This requires that each directory contains a header.html file.

3. Echo Command

The echo command can display the following environment variables:

DOCUMENT_NAME : Displays the name of the current document.

The result is:
index.html

DOCUMENT_URI : Displays the virtual path of the current document. For example:

The result is:

/YourDirectory/YourFilename.html

As your website continues to grow, those increasingly long URLs can definitely become a headache. If you use SSI, everything will be solved. Because we can combine the website's domain name with the SSI command to display the complete URL, that is:

http://YourDomain

QUERY_STRING_UNESCAPED: Displays the query string sent by the client without escaping, where all special characters are preceded by the escape character "\". For example:

DATE_LOCAL : Displays the date and time in the server's set time zone. Users can customize the output information by combining the timefmt parameter of the config command. For example:

The result is:

Saturday, the 15th of April, in the year 2019
DATE_GMT: Same functionality as DATE_LOCAL, except that the date returned is based on Greenwich Mean Time. For example:

LAST_MODIFIED: Displays the last update time of the current document. Again, this is a very useful feature in SSI. Just add the following line of simple text to the HTML document to dynamically display the update time on the page.

CGI Environment Variables

In addition to the SSI environment variables, the echo command can also display the following CGI environment variables:

SERVER_SOFTWARE : Displays the name and version of the server software. For example:

SERVER_NAME: Displays the server's host name, DNS alias, or IP address. For example:

SERVER_PROTOCOL: Displays the protocol name and version used by the client request, such as HTTP/1.0. For example:

SERVER_PORT : Displays the server's response port. For example:

REQUEST_METHOD : Displays the client's document request method, including GET, HEAD, and POST. For example:

REMOTE_HOST : Displays the name of the client host that issued the request information.

REMOTE_ADDR: Displays the IP address of the client that issued the request information.

AUTH_TYPE : Displays the authentication method of the user.

REMOTE_USER: Displays the account name used by the user accessing the protected page.

4. Fsize : Displays the size of the specified file. The output format can be customized by combining the sizefmt parameter of the config command.

5. Flastmod : Displays the last modification date of the specified file. The output format can be controlled in conjunction with the timefmt parameter of the config command.

Here, we can use the flastmod parameter to display the update date of all linked pages on a page. Here’s how:

<A href="/directory/file.html" rel="external nofollow" >File</A>

<A href="/another_directory/another_file.html" rel="external nofollow" >Another File</A>

The result is:
File April 19, 2019
Another File January 08, 2019

6. Exec

The Exec command can execute CGI scripts or shell commands. Here’s how to use it:
Cmd: Use /bin/sh to execute the specified string. If the IncludesNOEXEC option is used with SSI, this command will be blocked.
Cgi: Can be used to execute CGI scripts. For example, the following example uses the counter.pl script in the server's cgi-bin directory to place a counter on each page:
