Which of these page extensions WILL NOT recognize and execute an include file?
-
.shtml
-
.shtm
-
.stm
-
.html
-
.asp
Standard .html files are processed as static content by web servers and will not recognize or execute server-side include directives. The .shtml, .shtm, and .stm extensions are configured on servers to parse and process SSI directives. The .asp extension supports includes through ASP's specific #include directive, which is processed before the page executes. Plain .html files lack this server-side processing capability.
To answer this question, we need to understand the concept of server-side includes (SSI) and the file extensions that support them.
Server-side includes (SSI) allow web developers to include or insert the content of one file into another file during the server's response to a client's request.
Let's go through each option to understand which file extensions will not recognize and execute an include file:
Option A) .shtml - This option is correct. The .shtml extension is commonly used for files that contain server-side includes (SSI). It recognizes and executes include files.
Option B) .shtm - This option is correct. The .shtm extension is also commonly used for files that contain server-side includes (SSI). It recognizes and executes include files.
Option C) .stm - This option is correct. The .stm extension is also commonly used for files that contain server-side includes (SSI). It recognizes and executes include files.
Option D) .html - This option is correct. The .html extension does not typically recognize and execute include files. It is a static file extension and does not support server-side includes.
Option E) .asp - This option is incorrect. The .asp extension is commonly used for Active Server Pages (ASP) and supports server-side includes. It recognizes and executes include files.
The correct answer is Option D) .html. This option is correct because the .html extension will not recognize and execute include files.
