How can I rewrite this URL with Apache? - apache

I want to be able to access sitenamehere.com/folder/index?a=something by visiting sitenamehere.com/folder/something in my address bar.
How can I do this?
I've looked into mod rewrite but I don't understand it.

mod_rewrite is an Apache (web server) extension not related to PHP. You'll want to create a file called .htaccess and include the following line:
RewriteEngine On
RewriteRule ^folder/(.*) /folder/index.php?a=$1
http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html

Your .htaccess or httpd.conf.
# Turn on URL rewriting
RewriteEngine On
# Installation directory
RewriteBase /
# Your rule
RewriteRule ^([^/]+)/([^/]+)/?$ $1/index?a=$2 [L]
This assumes you want where folder is to be mapped over to where folder is in your example. If you want to match the literal folder, just replace the first capturing group with it (and add it to the replacement).

how do I rewrite a URL and maintain the file name

I have a rewrite written in my .htaccess file. I am trying to redirect the following
https://olddomain.com/folder/file.pdf to https://newdomain.com/folder/file.pdf. file.pdf can change so I need to change the domain but leave the folder and file name needs to stay what ever it is. it could be file.pdf or file1.pdf etc
I have this code in my .htaccess file
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/folder/(.*)$
RewriteRule ^(.*) https://newdomain.com/folder/%1 [R=301,NC]
If the file.pdf exists on the old server then the redirect works but if the file does not exist on the old server the redirect does not work.
Any help fixing this would be appreciated.
If the file.pdf exists on the old server then the redirect works but if the file does not exist on the old server the redirect does not work.
That sounds like you've put the rule/redirect in the wrong place. If you have other directives before this redirect that implement a front-controller pattern then you will experience this same behaviour since any request for a non-existent file would be routed to the front-controller (and request for an existing file is ignored) before your redirect is triggered - so no redirect occurs.
If this is the case then you need to move your rule to the top of the file, before any existing rewrites.
RewriteCond %{REQUEST_URI} ^/folder/(.*)$
RewriteRule ^(.*) https://newdomain.com/folder/%1 [R=301,NC]
However, your existing rule is not quite correct. Importantly, you are missing the L flag on the RewriteRule directive and the preceding RewriteCond directive is not required. For example, try the following instead:
RewriteRule ^folder/.* https://newdomain.com/$0 [NC,R=301,L]
This does assume your .htaccess file is located in the document root of the site.
Alternatively, you create an additional .htaccess file inside the /folder with the following:
RewriteEngine On
RewriteRule ^ https://newdomain.com%{REQUEST_URI} [R=301,L]
The REQUEST_URI server variable contains the full URL-path of the request (including the slash prefix).
By default, the mod_rewrite directives in the /folder/.htaccess file will completely override any directives in the parent (root) .htaccess file (the mod_rewrite directives in the parent are not even processed).

Htaccess rewrite to file located up one level

I have an htaccess in a subdomain with the following rule:
RewriteEngine On
RewriteBase /
RewriteRule ^feed([0-9]+)$ ../image.php?id=$1 [L]
So basically I want to redirect requests from feed which is located in a subdomain to image.php file which is located in the main domain (just one directory above). Using ../ doesn't seem to work like in PHP.
So how can I rewrite to file in the parent directory?
Thanks!
You can use mod_alias for this. Add the following directive to .htaccess file of subdomain:
AliasMatch "^/feed([0-9]+)$" "/absolute/path/to/image.php?id=$1"
Alternatively you can use symbolic links, but in my opinion AliasMatch directive is better.

Apache - rewrite images to php file with .htaccess

I'm looking for a way to rewrite all my image requests from one folder into some.php file, while preserving the original image url (or partial path).
So,
example.com/folder/img/test.jpg
would be rewrited as something like
example.com/folder/some.php?img=img/test.jpg
(is this the best approach?)
I'm not familiarized enought witrh regular expressions, so I'll be very thankfull :)
note : I've tried some solutions before, none of them worked. ALso, I'm running Apache 2.0 under CentOS environment.
Enable mod_rewrite and .htaccess through httpd.conf and then put this code in your .htaccess under DOCUMENT_ROOT directory:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteRule ^(folder)/(img/[^.]+\.jpg)$ $1/some.php?img=$2 [L,QSA,NC]
Make sure:
.htaccess is enabled
mod_rewrite is enabled
Your URL is http://example.com/folder/img/test.jpg
It sounds like you you want the filename of the image in the url to be included in the new php url, not the entire url. So something like:
RewriteRule ^folder/img/(.*[.]jpg)$ /folder/some.php?filename=$1
Considering what you mention in the comments and that the previous rules didn't work, I edited the message, this is what i have now.
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_URI} ^/(.*)\.jpg [NC]
RewriteRule ^folder/img/([\w]*\.jpg)$ folder/some.php?img=img/$1[R=301,L]
If folder is al variable, you can change that for (\w*) and add the reference in the right side of the rule.
Hope this helps.
Bye

Apache Rewrite: favicon in %{HTTP_HOST} directory

My software supports multiple domains pointed at the exact same directory, I use shared hosting. I need to have each domain's favicon load from directories with their respective host names. Here is a visual...
http://www.example1.com/favicon.ico
public_html/www.example1.com/favicon.ico
\
http://www.example2.com/favicon.ico
public_html/www.example2.com/favicon.ico
\
http://www.example3.com/favicon.ico
public_html/www.example3.com/favicon.ico
I've tried some rewrites along the lines like this without any success...
RewriteEngine on
RewriteRule ^favicon\.ico$ %{HTTP_HOST}/favicon\.ico
Things to keep in mind...
1.) I use shared hosting so remember that the answer I need should be short and simple.
2.) I will only accept a DYNAMIC answer, I will only use the %{HTTP_HOST} variable and NOT a static domain name as I will not be manually editing my .htaccess file every single time I add a domain name.
3.) I may end up putting a .htaccess file in those sub-directories though I do not at the moment, an exception for the favicon would be greatly appreciated though is not necessary for me to accept the answer.
4.) I'll be more than happy to make any clarifications.
Use this code:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteRule ^(favicon\.ico)$ %{HTTP_HOST}/$1 [L,NC]
I have been struggling with this issue too but I finally fixed it using the following rule:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^/favicon\.ico$ /sites/all/themes/mytheme/favicon.ico
</IfModule>
I stuffed this into a virtual host declaration. You can do this for each of your virtual hosts, all you need to do is point the second part to the correct icon!
This solves all of my favicon problems, even for Firefox :)
(Tested on FF25, Safari 6.1, IE8 and IE10)
This one worked better in my case
RewriteCond $0 !=images/favicon.ico
RewriteRule ^([^/]+/)*favicon\.ico$ /images/favicon.ico [L,NC]
To support all possible browsers and platforms, in addition to favicon.ico file, need to have files such as android-chrome-192x192.png, apple-touch-icon.png, favicon-32x32.png, etc...
Here is rewrite rule to support them all:
RewriteRule ^(favicon.*\.(ico|png)|apple-touch-icon.*\.png|android-chrome.*\.png|mstile.*\.png|safari-pinned-tab.*\.svg)$ /favicons/%{HTTP_HOST}/$1 [L,NC]
This will serve favicons including Apple Touch, Android Chrome, Windows and other favicons from /favicons/<DOMAIN_NAME> folder.
I had a problem with favicon in files on subdomain
I was struggling with redirect for favicon in htaccess for only one subdomain for a long time.
My case was that all domain take favicon from public/ directory. One subdomain (let's call it 'subdomain_a') is configured to take it from another directory and it works.
Problem appeared when a file was opened on subdomain_a. The favicon in file view (f.e. pdf-viewer) was taken from public/ directory, not from configuration of subdomain_a.
Here is my solution:
# Redirect for favicon
RewriteCond %{HTTP_HOST} ^www.subdomain_a.com
RewriteCond %{REQUEST_URI} ^/favicon.ico$
RewriteRule ^(.*)$ /path/to/favicon/for/new/domain/$1 [R=301,L]

Why is my .htaccess file redirecting to full server path instead of relative path?

I've never had a problem with cakePHP before, but something's odd about this server and is causing the redirects in the .htaccess files to behave oddly.
CakePHP uses mod_rewrite in .htaccess files to redirect requests to its own webroot folder. The problem is that the redirects are listing the wrong path and causing a 404 error. My CakePHP application, which is stored in the listings directory, has a .htaccess file as follows:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ app/webroot/ [R=301,L]
RewriteRule (.*) app/webroot/$1 [R=301,L]
</IfModule>
(*note that the R=301 causes an external redirect so we can see what is going on from our end. It should really omit this flag and do the redirect internally, transparent to end-users)
This is supposed to redirect any request from http://hostname.com/~username/listings/ to http://hostname.com/~username/listings/app/webroot/
However, rather than simply adding “app/webroot/” to the end as it is supposed to, it is adding the full server path ( /home/username/public_html/listings/app/webroot/ ) resulting in the final URL http://hostname.com/home/username/public_html/listings/app/webroot/ which is obviously incorrect and triggers a 404 error.
The hosting is on a shared hosting account, so that limits what I can do with the settings. I've never seen this happen before, and I'm thinking it's something wrong from the hosting side of things, but if anyone has some helpful suggestions then I can put them to the hosting company as well.
The solution to your question can be found towards the bottom of this page in the cakephp book:
For many hosting services (GoDaddy, 1and1), your web server is actually being served from a user directory that already uses mod_rewrite. If you are installing CakePHP into a user directory (http://example.com/~username/cakephp/), or any other URL structure that already utilizes mod_rewrite, you'll need to add RewriteBase statements to the .htaccess files CakePHP uses (/.htaccess, /app/.htaccess, /app/webroot/.htaccess).
I've deployed CakePHP from my profile's public_html folder as well. I had to change 3 the same .htaccess files mentioned above. Just add RewriteBase /~username/ to the .htaccess files just after RewriteEngine on!
Try removing .htaccess from main file... It worked for me
It was quite simple (using uolhost shared host):
Edit both .htaccess files:
/webroot/.htaccess
/.htaccess
Add the following line:
RewriteBase /
Here is the whole /webroot/.htaccess file:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
