.Htaccess - Redirect Subdomain to Folder

.htaccess - Redirect subdomain to folder

I have set CNAME of my sub domain below:

blog.mydomain.com

to my wordpress that installed in folder /blog/ under root directory.

Formerly I need to use this url to call wordpress:

http://blog.mydomain.com/blog/

which is ugly. I have tried many code to redirect:

http://blog.mydomain.com/

to the folder so I can use it as my wordpress url.

Finally I got .htaccess setting that is work:

    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^blog\.mydomain\.com$
    RewriteCond %{REQUEST_URI} !^/blog/
    RewriteRule (.*) /blog/$1

I have also CNAME other subdomain: http://forum.mydomain.com to mybb installation in folder /forum/mybb/ so the .htaccess need to put [L] on each of RewriteRule code as below.

    RewriteEngine On

    RewriteCond %{HTTP_HOST} ^forum\.tophyips\.info$
    RewriteCond %{REQUEST_URI} !^/forum/mybb/
    RewriteRule (.*) /forum/mybb/$1 [L]

    RewriteCond %{HTTP_HOST} ^blog\.tophyips\.info$
    RewriteCond %{REQUEST_URI} !^/blog/
    RewriteRule (.*) /blog/$1 [L]

In case you want to use the code please don't forget to set the site url and cookie path in the application config file follow to the setting to make the redirection work properly.

.htaccess redirect subdomain to directory

To map example.com or www.example.com to /front and sub.example.com to /subdomain folder, you can use these rules :

RewriteEngine on

#rewrite main domain to /front folder
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule !front /front%{REQUEST_URI} [NC,L]
#subdomain to /subdomain folder
RewriteCond %{HTTP_HOST} ^sub\.example\.com$
RewriteRule !subdomainfolder /subdomainfolder%{REQUEST_URI} [NC,L]

Redirecting subdomain to subdirectory through htaccess

Try this in your .htaccess:

RedirectMatch 301 wiki.comp.tf(.*) comp.tf/wiki$1

If that does not work, an alternative option is:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^wiki.comp.tf
RewriteRule ^(.*)$ http://comp.tf/wiki$1 [L,NC,QSA]

Some potential options for you using actual names:

Redirect 301 wiki.comp.tf comp.tf/wiki

Subdomain redirect to the sub directory with folder name .htaccess

for First condition use,

RewriteRule ^()$ /subdomains/index.php?user=$1

and for Second condition use,

RewriteRule ^mycategory$ /subdomains/category.php?user=$1

Redirect subdomain and folder by htaccess

HTTP_HOST only matches host/domain name. It doesn't match URI.

You may use:

RewriteCond %{HTTP_HOST} ^it\.(example\.com)$ [NC]
RewriteRule ^it(?:/|$) https://%1%{REQUEST_URI} [R=301,L,NE.NC]

htaccess redirect all subdomains to the same directory

Your above .htaccess would externally redirect the calls, as you use a full URL as the target.

In your question you say you want to keep the hostname, so I will assume that is the requirement.

0) Enable rewrite engine

RewriteEngine On

1) Rewriting known subdomains to their directory in /subdomains

# Rewrite known subdomains to /subdomains/{subdomain}/
RewriteCond %{HTTP_HOST} ^([^/.]+)\.example\.com$
RewriteCond %{REQUEST_URI} !^/subdomains [NC]
RewriteCond %{REQUEST_URI} !^/404 [NC]
RewriteRule ^(.+)$ /subdomains/%1/ [L]

1. When we encounter a request with a subdomain,
2. and we have not rewritten it to /subdomains
3. and we have not rewritten it to /404
4. then rewrite it to /subdomains/{subdomain}/

So, if the request was

http://foo.example.com/hello

the URL in the browser would stay the same, but internally be mapped to

/subdomains/foo/

2) Rewriting unknown subdomains to /404

# Rewrite missing unknown subdomains to /404/
RewriteCond %{HTTP_HOST} ^([^/.]+)\.example\.com$
RewriteCond %{REQUEST_URI} ^/subdomains [NC]
RewriteCond %{REQUEST_URI} !^/404 [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ /404/ [L]

1. When we encounter a request with a subdomain,
2. and we have already rewritten it to /subdomains
3. and we have not rewritten it to /404
4. and it is not existing as a file
5. and it is not existing as a directory
6. and it is not existing as a symlink
7. then rewrite it to /404

So, if the request was

http://bar.example.com/hello

the URL in the browser would stay the same, but internally be mapped to

/subdomains/bar/

by the first RewriteRule from 1).

If /subdomains/bar/ does not exist, the second RewriteRule from 2) will kick in and internally map it to

/404/

3) Test-Environment

I actually tested all of this with exemplary code, available here: https://github.com/janpapenbrock/stackoverflow-36497197
