using htaccess rewrite dynamic urls & category url - .htaccess

I want to know how to match a dynamic URL to a static URL using htaccess. but its's work from one RewriteRule but it doesn't work with second RewriteRule. How can i fix this.
I want it like this
contact.php to example.com/contact
category.php?url=some-url to example.com/some-url
My htaccess file
<Files .htaccess>
order allow,deny
</Files>
Options -Indexes
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteRule ^([^/]*)$ category.php?url=$1 [NC,L]
RewriteRule ^([^\.]+)$ $1.php [NC,L]

There are a number of issues with your approach. Most important: you appear to have understood the logic of rewriting rules the wrong way round...
Here is an example to get you started, you probably with have to adapt it to your specific setup:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^/?(.+)$ $1.php [END]
RewriteCond %{QUERY_STRING} (?:^|&)url=(.+)(?:&|$)
RewriteRule ^/?category\.php$ /%1 [END]
In case you receive an internal server error (http status 500) using the rule above then chances are that you operate a very old version of the apache http server. You will see a definite hint to an unsupported [END] flag in your http servers error log file in that case. You can either try to upgrade or use the older [L] flag, it probably will work the same in this situation, though that depends a bit on your setup.
This rule will work likewise in the http servers host configuration or inside a dynamic configuration file (".htaccess" file). Obviously the rewriting module needs to be loaded inside the http server and enabled in the http host. In case you use a dynamic configuration file you need to take care that it's interpretation is enabled at all in the host configuration and that it is located in the host's DOCUMENT_ROOT folder.
And a general remark: you should always prefer to place such rules in the http servers host configuration instead of using dynamic configuration files (".htaccess"). Those dynamic configuration files add complexity, are often a cause of unexpected behavior, hard to debug and they really slow down the http server. They are only provided as a last option for situations where you do not have access to the real http servers host configuration (read: really cheap service providers) or for applications insisting on writing their own rules (which is an obvious security nightmare).

how to rewrite url index.html to /home in htaccess

i want to rewrite url with index.html to /home, right now my url is like this https://xxxx.com/index.html, i want to convert it as https://xxxx.com/home , can anyone please help me how to do this in htaccess ? here i did some work for it but it is not working can anyone please help me how to do it ? any help will be really appreciated, this is what i tried with the code
CheckSpelling Off
AddType x-httpd-php56 .php
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteRule ^index\.html$ /home [NC,R,L]
Nearly perfect, but you need to add the internal rewriting the other way 'round... The incoming request is what you want to rewrite, so a request to /home...:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,END]
RewriteRule ^/?index\.html$ /home [R=301,END]
RewriteRule ^/?home/?$ /index.html [END]
It is a good idea to start out with a 302 temporary redirection and only change that to a 301 permanent redirection later, once you are certain everything is correctly set up. That prevents caching issues while trying things out...

Mod-rewrite rule which just gets the part of the URL after the =

I'm currently trying to redirect this URL
http://dev.example.org/active/researchers/contact.php?IDENT=12345
to
http://portaldev.example.org/users/ident/12345
in htaccess.
However, I can only get a redirect to
http://portaldev.example.org/users/ident/IDENT=12345
because I can't find a way to get rid of the IDENT=. How can I do that?
The rewrite conditions in my htaccess are:
RewriteCond %{REQUEST_URI} ^/active/researchers/contact\.php$
RewriteCond %{QUERY_STRING} ^IDENT=([0-9]*)$
RewriteRule ^(.*)$ http://portaldev.example.org/users/ident/$2 [R=302,NC,L]
This probably is what you are looking for:
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)IDENT=(\d+)(?:&|$)
RewriteRule ^/?active/researchers/contact\.php$ http://portaldev.example.org/users/ident/%1 [R=302,QSD,NC]

Got the answer to my question for anyone else who needs help:
RewriteCond %{REQUEST_URI} ^/active/researchers/contact\.php$
RewriteCond %{QUERY_STRING} ^IDENT=(.*)
RewriteRule (.*) http://portaldev.cepr.org/users/ident/%1? [R=301,L]
I think the main thing was the ? at the end of the rewrite rule but it also wouldn't work unless I put in the first RewriteCond to request uri and used (.*) in the rewrite rule

htaccess rewrite rule with condition and rewrite

I have a site that currently redirects to the public folder from root /
like so...
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^$ public/ [L]
RewriteRule (.*) public/$1 [L]
RewriteRule ^(.*).php$ /$1 [R=301,L]
I would like to add an exception for a system folder that needs to redirect to a different folder named 000999
RewriteCond %{REQUEST_URI} !/system [NC]
RewriteRule ^system/(.*)$ /000999 [L,NC]
However the exception whether placed after "Rewrite Base" or anywhere else fails to redirect
From your description and the example I understand that if the "folder" system is requested, regardless of the path below, there should be an internal rewrite to the folder /000999? Not a redirection? And the path should be ignored?
This should do, note that I also fixed a couple of other issues with your current setup:
RewriteEngine On
RewriteBase /
RewriteRule ^/?(.*)\.php$ /$1 [R=301]
RewriteRule ^/?system/(.*)$ /000999 [END]
RewriteRule ^/?(.*)$ /public/$1 [END]

Rewriting .htaccess to remove sub-directory from URL

I want to mask a folder in URL, so instead of www.mysite.com /employers/university-of-worcester/profile.html there would be www.mysite.com /university-of-worcester/profile.html , meaning that sub-directory "employers" is hidden.
There will be many folders created inside "employers" folder.
This is a matter of modifying .htaccess, I have tried a lot of solutions that I have found on stack.
The latest line of code I tried to add is:
RewriteRule ^employers/(.*)$ /$1 [L]
My .htaccess looks like this now:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^employers/(.*)$ /$1 [L]
</IfModule>
If I go to URL www.mysite.com/employers/ this will redirect to www.mysite.com/ (the homepage), which I am happy about, but if I try www.mysite.com/university-of-worcester/profile.html I get "The page can’t be found.", but the home profile.html is definitly inside "university-of-worcester" folder.
I am using wordpress.
This probably is what you are looking for:
RewriteEngine on
RewriteRule ^/employers/?(.*)$ /$1 [R=301,QSA]
RewriteCond %{REQUEST_URI} !^/employers/
RewriteRule ^/?(.*)$ /employers/$1 [END,QSA]
This will redirect direct requests to that folder and internally rewrite requests to that folder.

htaccess url with regex to forbidden

I need to block all request made with a specific url like
http://www.domain.est/-p-.html?slave_id=15265&osCsid=6j0ltvo8d9i8h30koahqusvua7
I tried with
RewriteCond %{THE_REQUEST} /(\/-p-\.html)+(\?slave_id\=\d{1,6})?(\&osCsid\=\w{1,26})? [NC]
RewriteRule ^ - [F]
but doesn't work.
Where I'm wrong ?
Thanks
This is a version that is easier to handle and should be more robust too:
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/-p-\.html$ [NC]
RewriteCond %{QUERY_STRING} slave_id=[0-9]{1,6}
RewriteCond %{QUERY_STRING} osCsid=[0-9a-z]{1,26}
RewriteRule ^ - [F]
Note: the query args matching patterns are not absolutely precise, but should be robust enough for almost all situations...
For this to work the http servers rewrite module has to be enabled, obviously. The rules will work in the http servers host configuration or in dynamic configurtation files (.htaccess). In case you decide to use such a dynamic configuration file you also have to take care to enable the interpretation of such files with the AllowOverride directive in the host configuration and the file has to be located in your http hosts configured DocumentRoot folder.
And a general hint: you should always prefer to place such rules inside the http servers host configuration instead of using dynamic configuration files (".htaccess"). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only provided as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).
