.htaccess rewrite if nothing specified - .htaccess

I'm trying to modify my .htaccess file to link to three different places, based on the input after the endpoint:
"/api" - Link to the API
"/ABCD123" - If it's a 7 character
alphanumeric string, link to a specific page
"/" - If nothing specified, or for any other inputs link to the homepage.
Here is my .htaccess file:
Options -Indexes
RewriteEngine On
RewriteRule ^api/(.*) ./api/index.php [R,L]
RewriteRule ^([a-zA-Z0-9]{7})$ index.php?l=$1 [L]
RewriteRule ^(.+)$ everythingelse.php [L]
Even though I have the [L] flag specified I always seem to get redirected to the everythingelse.php route, even if I have the 7 character string.
How can I rewrite to match this correctly?

Your rules are looping and executing more than once. L flag only breaks current loop but mod_rewrite can loop again and execute all the matching rules.
Options -Indexes
RewriteEngine On
# skip all files and directories from rewrite rules below
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^api/(.*)$ /api/index.php [R,L]
RewriteRule ^([a-zA-Z0-9]{7})$ index.php?l=$1 [L,QSA]
RewriteRule . everythingelse.php [L]

Rewrite rule in htaccess is not working

Here are the .htaccess rules:
RewriteEngine On
RewriteRule ^([^/]*)$ content.php?seourl=$1 [L]
RewriteRule ^pdf/([^/]*)$ content-single.php?seourl=$1 [L]
RewriteRule ^browsepdf$ browse.php [L]
RewriteRule ^browsepdf-([^/]*)$ browse.php?page=$1 [L]
RewriteRule ^download/([^/]*)$ download.php?pdf=$1 [L]
RewriteRule ^sitemap.xml$ xmlsitemap.php [L]
Options -Indexes
Here every URL is pointing to content.php?seourl=$1, even css, js and image files.
Here are some example URLs I need,
http://example.com/sjskjfsk21
http://example.com/asfasfasf43sf
http://example.com/pdf/fhfdhdh3432aaf
http://example.com/pdf/aisfyiahm2faf3
http://example.com/browsepdf
http://example.com/browsepdf-1
http://example.com/browsepdf-2
http://example.com/download/fjaskfjalsk3rs
http://example.com/download/usaydiy7aisydi
http://example.com/sitemap.xml
Can anyone please fix the .htaccess file.
Here every url is pointing to "content.php?seourl=$1"
Because your first (generic) rule catches all the requests. You need to change the order so you have the most specific rules first, and the most generic (catch-all) rules at the end. In your case you just need to move the first rule to the end. For example:
RewriteRule ^pdf/([^/]*)$ content-single.php?seourl=$1 [L]
RewriteRule ^browsepdf$ browse.php [L]
RewriteRule ^browsepdf-([^/]*)$ browse.php?page=$1 [L]
RewriteRule ^download/([^/]*)$ download.php?pdf=$1 [L]
RewriteRule ^sitemap\.xml$ xmlsitemap.php [L]
RewriteRule ^([^/]*)$ content.php?seourl=$1 [L]
NB: I backslash-escaped the dot in sitemap.xml to match a literal dot, otherwise it matches any character.
even css, js and image files.
You can make an exception for these static resources at the beginning of your file, before the existing directives. For example:
RewriteRule \.(js|css|png|jpg|gif)$ - [L]
For any URL that ends in any of the stated file extensions then stop processing the current mod_rewrite rules.
Alternatively (although perhaps marginally less efficient), you can prevent processing of requests for files that exist. Again, this goes before your existing mod_rewrite directives. For example:
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
However, this must now check every request for the existence of a file on the filesystem that maps to the request. (It could also be combined with the above rule if required.)
UPDATE: Bringing this together, we have:
# Exclude any existing files from being rewritten
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
# Specific rewrites
RewriteRule ^pdf/([^/]*)$ content-single.php?seourl=$1 [L]
RewriteRule ^browsepdf$ browse.php [L]
RewriteRule ^browsepdf-([^/]*)$ browse.php?page=$1 [L]
RewriteRule ^download/([^/]*)$ download.php?pdf=$1 [L]
RewriteRule ^sitemap\.xml$ xmlsitemap.php [L]
# Any other requests for the form "/<anything>"
RewriteRule ^([^/]*)$ content.php?seourl=$1 [L]

How to redirect a page with a query string to the homepage?

Recently I redesigned my site let's say http://www.sitename.com/ .
Before the redesign, the homepage url was something like this: http://www.sitename.com/default.asp?id=1&lg=1
Old pages had also weird query strings and they are not relevant any more, so, I want to redirect everything that begins with default.asp to the homepage.
RewriteRule default\.asp.* \
alternatively
RewriteCond %{QUERY_STRING} ^default.asp?id=1&lg=1$ [NC]
RewriteRule http://www.sitename.com/ http://www.sitename.com/? [R=301,L]
This is the closest I have got so far, but I am pretty sure its wrong.
Can you help?
Update: This is my whole .htaccess:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule default\.asp.* /?
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I have tried putting my rule at the top and at the bottom, (no luck). Should I embed it somehow on the other rule?
You can use these rules:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# redirect /default.asp to landing page
RewriteRule default\.asp$ /? [L,NC,R=301]
RewriteRule ^index\.php$ - [L,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>
# END WordPress
Based on this site, if you set up the rule like this
RewriteRule default\.asp.* /?
it should work.
Here is the reference for how you can replace query strings in the rewrite:
http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule
Modifying the Query String
By default, the query string is passed through unchanged. You can,
however, create URLs in the substitution string containing a query
string part. Simply use a question mark inside the substitution string
to indicate that the following text should be re-injected into the
query string. When you want to erase an existing query string, end the
substitution string with just a question mark. To combine new and old
query strings, use the [QSA] flag.
UPDATE
Based on your comment, try this:
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule default\.asp.*$ /? [L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
Note the [L] at the end of RewriteRule default\.asp.*$ /? [L] which terminates the rewriting process when that match is found. See L flag
If you don't include the L flag, then the process will continue with the rest of the rules in your .htaccess until it reaches the end with no matches or until it matches one with the L flag. Think of it like a switch statement, which needs a break in each case or else it continues to the next case, if it helps you.
default.asp is a filename you need to match against it using %{REQUEST_URI} variable. it's not part of querystring. To redirect requested URIs that contain default.asp ,you can use the following :
RewriteCond %{REQUEST_URI} /default\.asp [NC]
RewriteRule ^ http://sitename.com/? [R,L]

.htaccess and rewrite rule 404 not found

I'm new on .htaccess and rewrite rules.
So if my question is not relevant, please forgive me.
I have below htaccess code.
RewriteRule ^([^/]+)/([^/]+)/?$ article-list.php?link=$1&page=$2 [L,QSA]
If i visit url like www.example.com/category/0 it works.
But if i strip page url and last slash www.exapmle.com/category i see an ugly 404 page.
What is wrong with my htaccess directive?
Thanks in advance.
EDIT: Compeletely .htaccess
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
## If the request is for a valid directory
RewriteCond %{REQUEST_FILENAME} -d [OR]
## If the request is for a valid file
RewriteCond %{REQUEST_FILENAME} -f [OR]
## If the request is for a valid link
RewriteCond %{REQUEST_FILENAME} -l
## don't do anything
RewriteRule ^ - [L]
RewriteRule ^haber/([^/]+)-([^/]+)/?$ article.php?link=$1&i=$2 [L,QSA]
RewriteRule ^([^/]+)/([^/]+)/?$ article-list.php?link=$1&page=$2 [L,QSA]
This is a correct behaviour.
Actually, in a regular expression, a + means at least one.
When you use ([^/]+) it means at least one character which is not a slash.
Your rule ^([^/]+)/([^/]+)/?$ means at least one character which is not a slash / at least one character which is not a slash optional slash.
That's why it does not work with only the first part url.
If you also want to handle example.com/category you'll need another rule:
RewriteRule ^([^/]+)/?$ article-list.php?link=$1 [L]
RewriteRule ^([^/]+)/([^/]+)/?$ article-list.php?link=$1&page=$2 [L]

Cancel rewrite and redirect removing last directory with htaccess

I have a page with this settings:
Options All -Indexes
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /demo/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{REQUEST_URI} !^(.*)show(/|.*)$
RewriteRule . /demo/index.php [L]
</IfModule>
For example, when you request the page http://example.com/demo/any_folder/ it loads http://example.com/demo/index.php without changing the URL, to retrieve data from a database for example. Well, this works.
But I want to add and exception.
I need a condition that if you visit http://example.com/demo/any_folder/show it loads the same URL removing the word "show" but avoiding the redirect that is actually defined. So, it will load http://example.com/demo/any_folder/ and not http://example.com/demo/index.php. Does anyone know how to do this?
There has to be something different about the URL to not be redirected to index.php. The following .htaccess code adds a query parameter ?show to tell the two URLs apart.
Since, the redirection is internal; the user never gets to see the parameter.
RewriteEngine On
RewriteBase /demo/
RewriteRule ^index\.php$ - [L]
RewriteRule ^(.*)/show/?$ $1?show [NC,QSA,L]
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{QUERY_STRING} !^show [NC]
RewriteRule . /demo/index.php [L]

Force redirect for certain files (based on referer) and trigger a 404 page otherwise

We distribute different versions of a software product through a single download link. The delivery is based on the referer in conjunction with a default value, which works fine. In addition the user should be redirected to a 404-page, in case the wrong filename was used.
At the moment the .htaccess-file looks like this:
# stop directory listing
Options -Indexes
# turn rewrite engine on
RewriteEngine On
# force 404 if file name is missing or wrong
RewriteCond %{REQUEST_URI} !^(download_mac\.zip|download_pc\.zip)$
RewriteRule (.*) 404/index.html [L]
# an example based on the referer
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*domain-a\.com [OR]
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*domain-b\.com
RewriteRule ^(download_mac\.zip|download_pc\.zip)$ domain_ab/$1 [L]
# last rule if no referer matches
RewriteRule ^(download_mac\.zip|download_pc\.zip)$ default/$1 [L]
So I have one issue and one additional question with this file:
The first rule, to force 404, is very greedy and gets the error page every time, no matter what URL is called. I also tried single statements like RewriteCond %{REQUEST_URI} !^download_mac\.zip$ without any effect. How can I fix this?
How can I get rid of the filenames in any other rule? I tried things like RewriteRule ^(.*)$ default/$1 [L] but it gives me a hard time and an 500 Internal Server Error.
You can avoid repeating your filenames by using an Env variable like this:
RewriteRule ^(download_mac\.zip|download_pc\.zip)$ - [E=ALLOWED:$1,NC]
RewriteCond %{ENV:ALLOWED} ^$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ /404/index.html [L]
RewriteCond %{ENV:ALLOWED} !^$
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*domain-a\.com [OR]
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*domain-b\.com
RewriteRule ^ /domain_ab/%{ENV:ALLOWED} [L]
RewriteCond %{ENV:ALLOWED} !^$
RewriteRule ^ /default/%{ENV:ALLOWED} [L]
You can just move the rewrite rule to the end. The other rules handle the valid cases and if none of them matches the last rule applies
# an example based on the referer
RewriteCond %{HTTP_REFERER} ^http://([^.]+\.)*domain-[ab]\.com
RewriteRule ^download_(mac|pc)\.zip$ domain_ab/$0 [L]
# last rule if no referer matches
RewriteRule ^download_(mac|pc)\.zip$ default/$0 [L]
# force 404 if file name is missing or wrong
RewriteRule ^ 404/index.html [L]
