Description of my issue:

I have a test site in a subdirectory of 'x62, so the url would be http://mysite.com/x62.
I wanted "http://www.mysite.com/x62/" to go to this also (no 'www').

When I generate an .htaccess file for "www to non-www" it redirects to the main site of http://www.mysite.com and NOT the http://www.mysite.com/x62/

I've also attached a screen shot of the System Settings section of the .htaccess maker, if that is needed.

I believe this is the relevant portion of the .htaccess file. I've changed the actual site name.

Thanks.

First, it appears from reading that that rule does the opposite of what I want? It looks like it redirects anything from mysite.com/x62 to mysite.com This .htaccess file is in the mysite.com/x62 folder. There is a different .htaccess file in the mysite.com root folder.

Also, would this actually redirect anything other than a simple "www.mysite.com/x62/" ? For example, "www.mysite.com/x62/journey/" (to show a category of blog posts"?

I DID have to make an exception in the root folder's .htaccess file, to allow access to the entire "x62" folder to run kickstart.php when I was setting it up, by the way. I hadn't seen that documented anywhere.

Second, are you saying that this isn't a "bug" when setting up an htaccess file? I have other sites that also run from subfolders for other reasons, and I've had problems with them also regarding the www.mysite.com => mysite.com

I verified that the above rule does redirect ALL urls back to the "live" website.

Trying RedirectMatch 301 ^/x62/$ http://mysite.com/x62/ also doesn't work.

BTW, and option to "turn off" or "turn on" the .htaccess file would be useful in testing, as well as a "revert to last good version". Of course, I can do this by keeping Filezilla open at the same time, but it's not as convenient.

Additionally, it appears that I must also TURN OFF the "www to non-www" rule at the same time?

Thanks.

I think I'll just turn that off in the .htaccess maker and turn it on in the SEO component, at least for the test site.

I probably should have made a separate subdomain, but I'm not sure. Looking at the rules of how Apache finds and implements the .htaccess rules http://httpd.apache.org/docs/2.0/howto/htaccess.html (See "How directives are applied"), it's a little scary!

Do you have any favorite tool or website that you use to validate the regex expressions, etc?

##### Redirect www to non-www -- BEGIN
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R,L]
##### Redirect www to non-www -- END

I confess I haven't found the meaning for the %1 in the above rewrite rule. Why isn't it just
RewriteRule ^(.*)$ http://$1 [R,L] since variable '1' is everything AFTER the "www."?

** EDIT **
I wish I could edit the original post here, to have only a single "end of code" marker. It looks ugly! :(
