Simple and neat .htaccess redirect help required - .htaccess

This is a strange one...
A while back I managed to write a .htaccess redirect that worked so that the URL was read like: www.website.com/mt?page=index - and what the real URL of this page was www.website.com/PageParser.php?file=index.php
The problem has been that the FTP system of my webhost hides .htaccess files even though they are allowed and do operate - and so I have checked back on local copies I have of my .htaccess files and none of them have the code as to how this works - and I've forgotten how I did it!!
Essentially, I am using wildcards so that anything after mt?page= will actually be showing PageParser.php?file= but without having the PageParser.php showing within the URL (and this is the important bit, because the index.php on my site root is actually sent through PageParser.php first so that anything which shouldn't be there is wiped out before the end user sees it) - so how can .htaccess redirect/rewrite the URL so that any link to /mt?page= show the file located at /PageParser.php?file= without changing the URL the user sees?

RewriteEngine On
RewriteRule ^(.*)mt?page=(.*)$ $1PageParser.php?file=$2

RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^page=([^&]+)
RewriteRule ^mt$ /PageParser.php?file=%1.php [NC,L]
This rule will rewrite (internal redirect) request for /mt?page=hello to /PageParser.php?file=hello.php without changing URL in browser.
Your source URL example (www.website.com/mt?page=index) has index while target URL (www.website.com/PageParser.php?file=index.php) has index.php. The above rule will add .php to the page name value, so if you request /mt?page=hello.php it will be rewritten to /PageParser.php?file=hello.php.php.
If there is a typo in your URL example and page value should be passed as is, then remove .php bit from rewrite rule.
The rule will work fine even if some other parameters are present (e.g. /mt?page=hello&name=Pinky) but those extra parameters will not be passed to rewritten URL. If needed -- add QSA flag to rewrite rule.
This rule is to be placed in .htaccess in website root folder. If placed elsewhere some small tweaking may be required.
P.S.
Better write no explanation (I knew it/I did it before .. but now I forgot how I did it) than having these "excuses". While it may be 100% true, it just does not sound that great.

Htaccess replace one image with another one

So Ive been making a code which replaces one image with another without changing the link.
So heres the code that I found on one of the forums.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^.*/fredShip1.png$ /fredShip2.png [L]
</IfModule>
So this code not only redirects user to another page but also to a random link.
So original link is http://toss.rf.gd/storage/fredShip1.png though it should have replaced the image with http://toss.rf.gd/storage/fredShip2.png(Just an example) but it sends the user here toss.rf.gd/home/vol8_1/[Account info]/htdocs/storage/FredShip2.png
I added the image too ->
The image
I am really bad at htaccess so make sure correct me if Im wrong. Also english is not my first language so expect some minor mistakes.
EDIT : So i solved the problem with redirection to a random link. But Im still wondering is it possible to just change the image without changing the link?
RewriteRule ^.*/fredShip1.png$ /fredShip2.png [L]
The code you've posted already does essentially what you require, except that you need to adjust the paths to match your example. The "problem" with the above rule is that it rewrites the request to /fredShip2.png (in the document root), not /storage/fredShip2.png as in your example.
Assuming the .htaccess file is in the document root of the site and you wish to internally rewrite the request from /storage/fredShip1.png to /storage/fredShip2.png then you would do it like this:
RewriteRule ^storage/fredShip1.png$ storage/fredShip2.png [L]
There should be no slash prefix on the URL-path in either argument.
If you have other directives in your .htaccess file then the order of these directives can be important.
Make sure you've cleared your browser cache before testing.
but it sends the user here example.com/home/vol8_1/[Account info]/htdocs/storage/FredShip2.png
That's not possible with the directive you've posted. This is most likely a cached redirect due to an earlier (erroneous) experiment with 301 (permanent) redirects. For example, something like the following would produce the above "erroneous" output:
RewriteRule fredShip1\.png$ storage/FredShip2.png [R=302,L]
Note the use of the R (redirect) flag and the lack of a slash prefix on the RewriteRule substitution string (2nd argument). Since the substitution string is "relative", the directory-prefix (ie. /home/vol8_1/[Account info]/htdocs/ in your example) is prepended to substitution and since this is an external redirect (as denoted by the R flag) this then exposes the absolute filesystem path to the user.
NB: The above is a 302 (temporary) redirect - so should not be cached by the browser (at least not by default).

Why my rewrite rule in htaccess is working in some case only?

I try to rewrite some of my URLs with a .htaccess file but it didn't work as expected.
This is the rewrite rule in my .htaccess file :
RewriteRule ^(index|administration)/([A-Za-z0-9-]+)(\.php)?$ index.php?c=$1&t=$2 [QSA]
When I go on www.example.com/index/main, I get a 404 error code.
So I try to change my rewrite rule to
RewriteRule ^index.php$ index.php?c=index&t=main [QSA]
Then I go to www.example.com/index.php and the webpage displays perfectly with all the datas in $_GET (c = index and t = main).
So I don't know why my first rule is not working. Let me see if you have any idea.
Is it possible that my server wants to enter the index folder, then the main folder for my first rule without taking care of my .htaccess (www.example.com/index/main) ?
You need to ensure that MultiViews (part of mod_negotiation) is disabled for this to work correctly. So, add the following at top of your .htaccess file:
Options -MultiViews
If MultiViews is enabled (it's disabled by default, but some hosts do sometimes enable this in the server config) then when you request /index/main where /index.php already exists as a physical file then mod_negotiation will make an internal request for index.php before mod_rewrite is able to process the request. (If index.html also exists, then this might be found first.)
(MultiViews essentially enables extensionless URLs by mocking up type maps and searching for files in the directory - with the same basename - that would return a response with an appropriate mime-type.)
If this happens then your mod-rewrite directive is essentially ignored (the pattern does not match, since it would need to check for index.php) and index.php is called without the URL parameters that your mod_rewrite directive would otherwise append.
it perfectly works by disabling the MultiViews Option in my .htaccess
This would ordinarily imply its your script (ie. index.php) that is triggering the 404 (perhaps due to missing URL parameters?), rather than Apache itself?
However, if you were seeing an Apache generated 404 then it would suggest either:
You also have an index.html file, which is found before index.php. .html files do not ordinarily accept path-info (ie. /main) so would trigger a 404.
OR, AcceptPathInfo Off is explicitly set elsewhere in the config, which would trigger a 404 when the request is internally rewritten to /index.php/main (by mod_negotiation).

htaccess Rewrite rule to send variable info to script but display clean url

What I'd like to do is when a URL like
http://localhost/sandbox/jcsearch/country/countryname
is typed by the user I would like to to point to
http://localhost/sandbox/jcsearch/index.php?country=countryname
but still retain the original clean URL in the address bar ie
http://localhost/sandbox/jcsearch/country/countryname
Is this possible? would it create any kind of redirect loop?
The rewrite would happen as follows:
RewriteEngine on
RewriteRule ^sandbox/jcsearch/([^/]+)/([^/]+)$ sandbox/jcsearch/index.php?$1=$2 [L,NC]
Since, the RewriteRule directive does not have the redirection flag (R) set, it will not change the URL in your browser's addressbar. So, by visiting
http://localhost/sandbox/jcsearch/country/countryname
user will get internally redirected to:
http://localhost/sandbox/jcsearch/index.php?country=countryname
Please note: You have to put the rewrite rules in the htaccess file in your server root directory.

Redirect the URL using .htaccess file

I have a page showing the products with the hyperlink for it as
www.domainname.com/productname
now my client needs to add store and needs the URL to show as
www.domainname.com/store/productname
I have done it via code and now when I click on it for a detail page, its still redirecting to
www.domainname.com/productname
but need to be
www.domainname.com/store/productname
tried with this:
RewriteRule ^store/?$ domianname.com/?$ [NC,L]
in .htaccess file, not sure whether I'm on page
Can any one tell me how to do it via .htaccess file.
Your RewriteRule is backwards: you need the path you're matching first, then the path you're redirecting to. Try this:
RewriteRule !^/store/(.*) /store/$1 [NC,L]
Also, you don't actually need mod_rewrite to do this. You could try mod_redirect, which is simpler and easier to understand:
RedirectMatch !^/store/ /store/
(N.B. I haven't tried either of these, so I'm not 100% certain they do what you want.)

How do I do a htaccess rewrite to another folder for a single file?

We moved a part of our site from one sub folder to another. I want to put permanent redirects (301) into htaccess for the files in this folder (some have changed their filename as well, so I can't just setup one rule for the whole folder). Here's what I'm trying
RewriteRule ^search/tutorial-search.html$ db/tutorial.php [R=301]
This doesn't work though, I get a 404 response when now entering the old URL. I find this curious as I had a rule in place for ages that does work, which looks like this:
RewriteRule ^search/tutorial-search.html$ search/tutorial-search.php
I really don't see the big difference. I also tried the following (among others) but it doesn't work either
RewriteRule ^search/tutorial-search.html$ db/tutorial.php
What exactly is causing this to fail? Just to make sure I put all of these at the exact same line of the htaccess file. Is it because I'm rewriting to another folder? Thanks :)
Try adding a leading slash to your rewrite targets, because when redirecting, apache could be mistaking a URL-path with a file-path.
RewriteRule ^search/tutorial-search.html$ /db/tutorial.php [R=301]
