When (not) to use .htaccess files

In general, you should never use .htaccess files unless you don't have access to the main server configuration file. There is, for example, a prevailing misconception that user authentication should always be done in .htaccess files. This is simply not the case. You can put user authentication configurations in the main server configuration, and this is, in fact, the preferred way to do things.
.htaccess files should be used in a case where the content providers need to make configuration changes to the server on a per-directory basis, but do not have root access on the server system. In the event that the server administrator is not willing to make frequent configuration changes, it might be desirable to permit individual users to make these changes in .htaccess files for themselves. This is particularly true, for example, in cases where ISPs are hosting multiple user sites on a single machine, and want their users to be able to alter their configuration.
However, in general, use of .htaccess files should be avoided when possible. Any configuration that you would consider putting in a .htaccess file, can just as effectively be made in a <Directory> section in your main server configuration file.
There are two main reasons to avoid the use of .htaccess files.
The first of these is performance. When AllowOverride is set to allow the use of .htaccess files, Apache will look in every directory for .htaccess files. Thus, permitting .htaccess files causes a performance hit, whether or not you actually even use them! Also, the .htaccess file is loaded every time a document is requested.

Once you edit the file, you need to re-start Apache.

Hi,

I'm new.

May I know what is CRU format?

How to include [forum_id] in the CRU format? include through vBulletin control panel? or vbSEO control panel?

Thank you.

Regards,
Eric

I have an ignorant question: what is the topic for and how to apply it? (what's CRU...). Thanks.

CRU stands for "Content Relevant URL", which typically means that keywords related to the page topic are included in the URL.

Static or rewritten URLs are considered CRUs if they contain keywords.

You can configure your URL Rewriting for vBSEO within the control panel (vbseocp.php).

If this is true, it seems then that moving rewrite rules from .htaccess to httpd.conf might not actually result in much of a performance gain if AllowOverides is not also disabled, no?

No response to this observation/question?

I have moved the rewrite rules from .htaccess to httpd.conf, and I can see a very noticable improvement on performance.

Thanks for the suggestion!
