Is it possible to comment on one or more sections of an .htaccess file, like using /*
and */
in various programming languages?
Solution
Actually, .htaccess files only support single-line comments: the hash (#
) character at the beginning of a line tells the parser to ignore that line. For example:# this is a comment in an .htaccess file and many other scripting languages
However, from a practical perspective, it is possible to wrap several adjacent lines in an IF
block (available in Apache 2.4 and later). This effectively disables the lines within the block. For example:
<IF "false">
...disabled directives...
</IF>
That said, multi-line comments in many programming languages allow more or less any content within them, such as plain English text rather than executable code. In contrast, the content of an IF
block like the one above must consist of valid .htaccess directives and regular single-line comments. Otherwise, an HTTP 500 error will be generated.
What Is the Purpose of an .htaccess File?
Question:
When I downloaded a CMS, I noticed a strange file named .htaccess
. I’m curious whether this file is related to the CMS I downloaded and if deleting it will affect the CMS.
Answer:
The .htaccess
file is a configuration file used on web servers running the Apache Web Server software. When an .htaccess
file is placed in a directory that is then loaded by the Apache Web Server, it is detected and executed by the server.
The .htaccess
file can be used to modify Apache Web Server settings, such as enabling or disabling certain functions and features. Its capabilities include basic redirects (e.g., handling 404 errors for "file not found") as well as more advanced features, such as content password protection or preventing image hotlinking.
Deleting this file could potentially disrupt the functionality of your CMS, especially if the CMS relies on specific settings or rules defined in the .htaccess
file.
