Htaccess Filesmatch file overview

Question

I am trying to install drupal in a subdirectory of my website hosted on bluehost ...

This is a HUGE pain

I think the following lines from .htaccess is the problem. When I am currently navigatoe for mysite.com/subdir/install.php, I get error 403. However, when I output the “negation” from the lines below, I stop receiving this error, so I suspect that this line causes all Problems.

My question is: can someone help me understand what is happening in the following code? Especially if you can break it with a component.

<FilesMatch "\.(engine|inc|info|install|make|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl)(|~|\.sw[op]|\.bak|\.orig|\.save)?$|^(\..*|Entries.*|Repository|Root|Tag|Template)$|^#.*#$|\.php(~|\.sw[op]|\.bak|\.orig\.save)$"> Order allow,deny </FilesMatch> 

Answer 1

FilesMatch allows FilesMatch to match files using a regular expression.

In the FilesMatch above, you have 4 sets of regular expressions, where 1 set has an extra extra set.

Basically, this is denied access (error 403) to any of the found files that are described in your regular expression sets.

For instance:

 \.(engine|inc ...)$| 

So, if the file ends with .engine or .inc or ... the rest of the rule prohibits access to it.

Then at the end of the first set of rules you have | , which, as in the previous example, means OR , therefore, if the first set of rules does not match, it starts the second, which is slightly different.

 ^(\..*|Entries.*|Repository)$ 

Here it is done the other way around, it matches if the file starts and ends with the given keyword, for example:

If the file starts with . followed by something, ( .* ) means something else, such as .htaccess or begins with Entries , followed by something, or it’s for sure a repository or ... to the end.

Then the following rule ^#.*#$ , This means that the file begins and ends with the # symbol as # , which is processed literally

And the last set of rules does the same in the first scan if the file ends with the specified extensions.
