Is it possible to do a "reverse" mod_rewrite? - .htaccess

RewriteRule ^id/([^/]*)$ /product.cgi?id=$1 [L]
The above will execute example.com/product.cgi?id=* when url example.com/id/* is requested by the user. I would like the other way around,
i want to display to the user example.com/id/* when example.com/product.cgi?id=* is requested. Keeping in mind that example.com/id/* does not exist on the server, it would work line an alias. Is it even possible?

You can use this in your .htaccess to do the reverse.
RewriteEngine On
RewriteCond %{THE_REQUEST} [A-Z]{3,}\ /product\.cgi\?id=([^&\ ]+)
RewriteRule ^ /id/%1? [R=301,L]
RewriteRule ^id/([^/]*)$ /product.cgi?id=$1 [L]

RewriteRule for hiding file extension and change file name

starting url - example.com/vid.php
wanted url - example.com/video
any help, pls, to write the RewriteRule
RewriteCond %{THE_REQUEST} /vid\.php\s [NC]
RewriteRule ???
With your shown samples, please try following htaccess rules file. Make sure to clear your browser cache before testing your URLs.
Also make sure that your vid.php file is present alongside with htaccess rules file.
RewriteEngine ON
RewriteCond %{THE_REQUEST} \s/vid\.php\s [NC]
RewriteRule ^ video? [R=301,L]
RewriteRule ^video/? vid.php [NC,L]
You don't even need a separate RequestCond here...
RewriteEngine on
RewriteRule ^/?vid\.php$ /video [QSA,R=301,L]
RewriteRule ^/?video/? /vid.php [QSA,END]
Test with a fresh anonymous browser window.
It is a good idea to start out with a R=302 temporary redirection and only change that to a R=301 permanent redirection once you are satisfied.

RewriteRule to rewrite /folder/subfolder/file to /?f=folder/subfolder/file?

Pretty straightforward - just wondering how do I rewrite this:
/folder/subfolder/file
/?f=folder/subfolder/file
And the number of folders/subfolders might vary, so what I really want is anything after the / in that path (that does not already have ?f= in it) redirected to the path with ?f= added in front of it.
If I add this
RewriteRule ^(.*)$ ?f=$1 [L]
it works just fine but doesn't recognize the existence of ?f= in the URL already, and breaks that existing link with ?f= in there.
Any ideas?
You can use:
RewriteCond %{QUERY_STRING} !(?:^|&)f= [NC]
RewriteRule ^(.*)$ ?f=$1 [L,QSA]
Which does not do the rewriting if the f querystring is already there.
With [QSA] you keep the other possible querystring values.
Try this :
RewriteEngine On
RewriteRule ^(.[^\?]*)$ /?f=$1 [L]

ReWrite rule not working with two parametrs

im quite new to rewrite rules.
I can manage with one variable and thats it.
I have webpage Where the rewriterule is:
RewriteCond %{HTTP_HOST} ^www\.someserver\.com$
RewriteRule ^/?$ "http\:\/\/someserver\.com\/" [R=301,L]
RewriteRule ^(\d+)*$ ./index.php?comp=$1
RewriteRule ^(\d+)*/$ ./index.php?comp=$1
And it all work fine as it should. But now as i want 1 more variable into URL
i cant get it to work.
Right now the $1 is only numbers.
someserver.com/1554886
But i want two variable.
someserver.com/1554886-SOMENAME-WHATEVER-WORD-AND-HOW-MANY
But it wont show.
i tried smth like this:
RewriteRule ^([^-]*)-([^-]*)$ ./index.php?comp=$1&string=$2 [L]
How do i get it to work?
Do i have to make some changes in the php side as well?
everything what comes after the number part of the URL is there only for
SEO, the number is Unique
You need one more rule to handle two parameters:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(someserver\.com)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L,NE]
RewriteRule ^(\d+)/?$ index.php?comp=$1 [L,QSA]
RewriteRule ^(\d+)-(.+)/?$ index.php?comp=$1&string=$2 [L,QSA]

URL rewriting via my .htaccess file

How do I change example.com/1 to example.com/?id=1
I've tried googling but I can only find code for example.com/?id=1 to example.com/1
I used a generator and got this, but it didn't work
RewriteEngine On
RewriteRule ^\?get\=$ / [L]
Thanks,
Isaac
It kind of depends on which way you want to do the rewrite - ie, what does the user type see, and what does the server do.
If you want the user to see "http://example.com/1" and internally the server provides "http://example.com/?id=1", then the following should work:
RewriteRule ^([0-9]+)$ /?id=$1
However, if you want the user see "http://example.com/?id=1", and internally the server provides "http://example.com/1", then the following, as per Jon Lin's answer, should do it:
RewriteCond %{QUERY_STRING} ^id=([0-9]+)$
RewriteRule ^$ /%1?
You can't match against the query string in a RewriteRule statement, you need to use a RewriteCond and the %{QUERY_STRING} variable:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^id=([0-9]+)$
RewriteRule ^$ /%1? [L]
The ? is needed in the rule's target to remove the query string.

(htaccess) Rewrite English names of php files to their Dutch equivalents

I would like to rewrite the English names of php files to their Dutch equivalents.
For example: someurl.com/news.php?readmore=4#comments should become someurl.com/nieuws.php?leesmeer=4#kommentaar. The code from news.php should be executed but nieuws.php should be in the url the arguments should function as well.
I tried several htaccess examples but I can't get it to work.
Any help would be appreciated.
Edit: Working progress from answers below and final solution.
RewriteCond %{QUERY_STRING} ^readmore=(.*)$
RewriteRule ^news.php$ nieuws.php?leesmeer=%1 [R=301,L]
RewriteCond %{QUERY_STRING} !^norewrite[\w\W]*$
RewriteRule ^news.php$ nieuws.php [R=301,L]
RewriteRule ^nieuws.php$ news.php?norewrite [QSA]
RewriteCond %{QUERY_STRING} !^norewrite[\w\W]*$
RewriteRule ^search.php$ zoeken.php [R=301,L]
RewriteRule ^zoeken.php$ search.php?norewrite [QSA]
# make sure rewrite is activ
RewriteEngine On
# Rewrite a request for nieuws.php to news.php
RewriteRule ^nieuws.php$ news.php
Should do the trick.
Instad you could send all requests to an index.php and parse them there:
## Redirect everything to http://hostname/?path=requested/path
RewriteEngine On
RewriteRule ^([\w\W]*)$ index.php?path=$1 [QSA]
[QSA] makes sure you get the original get arguments too.
Now you have to parse the request in $_GET['path'] in you index.php and include the requested page.
eg:
if ($_GET['path'] == 'nieuws.php') {
include 'news.php';
} else if (empty($_GET['path'])) {
echo "HOME";
}
if you want to make make the user always sees nieuws.php in its address bar, even if he requested news.php, you could try the following:
RewriteEngine On
# Redirect news.php to nieuws.php if and only if the request comes from the client
# (suppose the client didn't set ?norewrite.)
RewriteCond %{QUERY_STRING} !^norewrite[\w\W]*$
RewriteRule ^news.php$ nieuws.php [R=301,L]
# Send news.php if nieuws.php was requested and prevent news.php from being redirected
# to back to nieuws.php by the rule above.
RewriteRule ^nieuws.php$ news.php?norewrite [L,QSA]
(R=301 means send a "moved permanently" redirect to the client, L means stop rewriting after this rule matched)
The hole thing with norewrite (you could use something else instead) is only needed to avoid an endles loop of rewriting between news and nieuws.
To translate the GET arguments, you can try the following code before the first line of the above code:
RewriteCond %{QUERY_STRING} ^readmore=(.*)$
RewriteRule ^news.php$ nieuws.php?lesseer=%1 [R=301,L]
Things after a the # in an url can't be changed in .htaccess, since they aren't send to the server at all. The only chance to change them is using JavaScript. (See lots of question here on manipulating them within JavaScript)
Try:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /news\.php
RewriteRule ^ /nieuws.php [L,R=301,QSA]
RewriteRule ^nieuws\.php$ /news.php [L,QSA]
