I'd like to setup an htaccess redirect rule which redirects the following pattern:
https://www.example.com/something/ABC123455
to
https://www.new-domain.com/something/ABC123455
while ABC123455 is a dynamic string which can include any upper cased letter and number with exactly 8 characters.
So I guess the regex for this would be:
([A-Z0-9]){8}
So I am looking into several guides:
Redirect to dynamic relative paths with .htaccess?
https://www.sitepoint.com/community/t/htaccess-redirect-with-dynamic-strings/74591
but all I learn is how to setup a route redirect via query parameter ?var=ABC and so on.
Can someone bring me to the right track here? It can't be that hard.
You may use this rule in site root .htaccess of old site:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(?:www\.)?example\.com$ [NC]
RewriteRule ^something/[A-Z\d]{8}/?$ https://www.new-domain.com/$0 [L,R=301]

I'm having an issue with some htaccess rules which I thought would be simple. I have some nice SEO friendly URL rewriting in place as below
RewriteEngine On
RewriteCond %{REQUEST_URI} !^(index\.php|/images|/templates|/views|/ajax|/uploads|/robots\.txt|/sitemap\.xml|/favicon\.ico|/scripts|/cron|/combine.php|/js|/css)
RewriteRule ^(.*)$ index.php?ref=$1&%{QUERY_STRING} [L]
This all works well and I want to keep this. I also wish to rewrite some old pages which Google WMT is reporting as 404's to the new equivalent and for that I'd like to use:
Redirect 301 /about_us http://example.com/about-us
The problem I have is that the URL that the browser is directed to is:
http://example.com/about-us?ref=about_us
The about_us is the old link and about-us is the correct link. If the htaccess redirected to example.com/about-us then the other SEO friendly rewrite rule will pick it up and show the page but eh extra ?ref= parameter is confusing it. I am guessing the two rules are conflicting to a degree but is there a way to get the two rules to work together e.g. redirect without the extra ?ref= parameter? My knowledge of htaccess is basic to say the least so I am a little stuck on this one.
Thanks in advance
Redirect and RedirectMatch are part of mod_alias, while the rewrite rules are part of mod_rewrite. The problem you're running into is when you mix the two, both modules affect the same request, thus two things happen when you only want one. In this case, you need to stick with just mod_rewrite and use this instead:
RewriteEngine On
RewriteRule ^about_us /about-us [L,R=301]
RewriteCond %{REQUEST_URI} !^(index\.php|/images|/templates|/views|/ajax|/uploads|/robots\.txt|/sitemap\.xml|/favicon\.ico|/scripts|/cron|/combine.php|/js|/css)
RewriteRule ^(.*)$ index.php?ref=$1&%{QUERY_STRING} [L]
Note that the rule that redirects comes before the rule that routes to index.php.
I want to redirect requests to the URL:
example.com/downloads
to
download.example.com/downloads
How can I write a regex rule for this for an .htaccess file?
You don't actually need mod_rewrite to do this. Nor do you need a regex, unless you're matching a pattern instead of just a string.
Redirect ^/downloads http://download.example.com/downloads
If you need to match a pattern (i.e. redirect each subdirectory to a subdomain - sounds like a bad idea to me, but whatever) then you do need a regex, but you still don't need mod_rewrite.
RedirectMatch ^/([^/+])(/.+)? http://$1.example.com/$1$2
This matches a string immediately following the domain, i.e. the "downloads" part of http://example.com/downloads/somefile, then any trailing part of the request, and builds an URL to redirect to using those two pieces.
Place this rule in your root .htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^downloads(/.*)?$ http://download.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L,NC]
Could someone tell me how to rewrite this URL. I have looked at a lot of questions on stackoverflow but they seem to be missing my answer.
RewriteEngine On
That is what I have... its a bit poor.
I need to rewrite url's if they do not point to a directory.
I need to do this...
any.domain.com/pages/some-page-slug/login
To be rewritten to the correct url of...
any.domain.com/pages/login.php?page=32
Does anyone have any ideas on how this can be achieved?
1) Rewriting product.php?id=12 to product-12.html
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ product.php?id=$2
3) Redirecting non www URL to www URL
If you type yahoo.com in browser it will be redirected to www.yahoo.com. If you want to do same with your website then put the following code to .htaccess file. What is benefit of this kind of redirection?? Please check the post about SEO friendly redirect (301) redirect in php and .htaccess.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^optimaxwebsolutions\.com$
RewriteRule (.*) http://www.optimaxwebsolutions.com/$1 [R=301,L]
4) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
5) Redirecting the domain to a new subfolder of inside public_html.
Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
TO do this you need to write a front controller.
See here, here, here, and here.
Alternatively in Apache you can rewrite this
any.domain.com/pages/32/login
or this:
any.domain.com/32/login
or even this:
any.domain.com/some-slug/32/login
to this:
any.domain.com/pages/login.php?page=32
One way or another to do this with only apache you need to supply the page id in some fashion. Keep in mind even with format any.domain.com/some-slug/32/login the content of the slug is irrelevant and won't necessarily link to the correct page. Which I imagine is undesirable and bad for SEO.
Another alternative is using RewriteMap. But this will be tricky and require reloading apache configurations whenever a page/slug is created/edit.
I understand that pages and login are static in this case and some-page-slug is changing. And you always want to redirect to static page /pages/login.php?page=32
So this is how to do it:
1) Rewrite
RewriteEngine On
RewriteRule ^pages/([a-zA-Z0-9_]+)/login(.*)$ /pages/login.php?page=32
or 2) Redirect Pernament
RewriteEngine On
RewriteRule ^pages/([a-zA-Z0-9_]+)/login(.*)$ /pages/login.php?page=32 [R=301,L]
or 3) Redirect Temporary
RewriteEngine On
RewriteRule ^pages/([a-zA-Z0-9_]+)/login(.*)$ /pages/login.php?page=32 [R=302,L]
Here is great article about htaccess trics
http://perishablepress.com/press/2006/01/10/stupid-htaccess-tricks/
I want accesses to e.g. www.thisdomain.com/docs/path1/path2 to redirect to www.thatdomain.com/path1/path2
(Note that docs is not a part of the new path)
I have the following on www.thisdomain.com:
RewriteEngine on
RewriteRule ^docs/* http://www.domain.com/ [R=301,L]
If I access www.thisdomain.com/docs, it directs to www.thatdomain.com, but if I access a child-path like www.thisdomain.com/docs/path1/path2 it fails. Is it possible for the redirect to intercept the child-path access and redirect as I need? If so, any pointers?
Thanks.
With regular expressions, * means any number of the previous atom, which will match /docs and /docs/. Try this:
RewriteEngine on
RewriteRule ^docs$ http://www.domain.com/ [R=301,L,QSA]
RewriteRule ^docs/(.*) http://www.domain.com/$1 [R=301,L,QSA]
(QSA is query string append, so /docs/foo?bar=baz won't lose the ?bar=baz.)
According to section "Redirect Old domain to New domain using htaccess redirect" of the first Google result which I found searching for "htaccess redirect" (without the double quotes), this piece of code will suffice:
Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]
According to their description of the technique, it will redirect the directory the .htaccess file is placed in recursively (including any child paths), just as you intend. Of course, mod_rewrite needs to be present for the rewrite directives to work.
I'm restructuring a web site with a great deal of content currently parked at URLs that look like this.
http://string.domain.com/year/month/dd/string-pulled-from-title
For various reasons, I'd like to park all new content at URLs that looks like this
http://www.domain.com/blogs/string/year/month/dd/string-pulled-from-title
I'd like to make the change for future content, but don't want all the old stuff to go 404.
I believe a 301 redirect rule in my htaccess will do the trick, sending all referred traffic coming in through old links to the new formats.
But what should this rule look like? I've read a few tutorials but haven't found this exact case in any examples.
Note, I don't want to do this for all subdomains, only for about 10 specific ones. So if someone could help me figure out one of these, then I can copy paste it 10 times in my htaccess for each subdomain and be set.
Drop this into the .htaccess file of the old site (adjusting the domain to your actual one):
RewriteEngine On
RewriteRule ^(.*)$ http://example.com/blogs/string/$1 [R=301]
This will grab this part of the URL at the old site:
year/month/dd/string-pulled-from-title
and redirect it to the new site under the new location:
blogs/string/year/month/dd/string-pulled-from-title
Alternatively, if you want something a little more variable like, without having to custom fix each .htaccess, drop this in the file for each subdomain instead:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(.*).example.com
RewriteRule ^(.*)$ http://example.com/blogs/%1/$1 [R=301,L]
If you're redirecting to the same domain, and it includes the www, adjust the rewrite rules to the following:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(.*).example.com
RewriteCond %{HTTP_HOST} !^www.example.com [NC]
RewriteRule ^(.*)$ http://example.com/blogs/%1/$1 [R=301,L]
Note the second RewriteCond which checks to make sure that the URL requested does not include the leading www, which may lead to an endless redirect if the destination URL itself includes www and would try and redirect that subdomain as well.
%1 grabs the first capture group from the line above.
$1 references the first capture group on the same line.
