Mode Rewrite; with/without trailing slash on end of url? - .htaccess

I basically tried this mode_rewrite rule below. It works with a slash on the end but I want it to work whether it has a trailing slash on the end or not. Basically I want it like this as some people see it as normal with a slash on the end and others don't hence why I want it to work whether it's there or not.
RewriteRule ^signup/register(.[^/]*) /signup/register.php [NC]
Basically it will work like http://localhost/signup/register/ but if I remove the / from the end it gives 404 error.

The subpattern .[^/]* requires at least one arbitrary character. In your case it’s probably that trailing slash.
You should better stick to one writing (either with or without trailing slash) and redirect th wrong writing to the proper, like:
# remove trailing slash
RewriteRule ^(.*)/$ /$1 [L,R=301]
# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^.*[^/]$ /$0/ [L,R=301]

plain old regexes:
RewriteRule ^signup/register/?$ /signup/register.php [NC]

...
RewriteRule ^(url-rewrite)/?$ page.php [NC]
...
The ? after / specifies that there can be none or one / after your url-rewrite, as such it would accept it with or without the trailing /

How to escape characters in wildcard in htaccess

I have a htaccess file which is used for earning money by short links, as the following code:
RewriteEngine On
RewriteRule (.*) http://shortlink.com/s/N9IpzM7J?s=$1 [R=301]
But with above code, it'll redirect example.com/https://google.com to http://shortlink.com/s/N9IpzM7J?s=https:/google.com notice it that it lost a slash at https://, in my thought, it might be a special character in htaccess but I don't know how to escape it.
So I want to ask how to let the above code works which will redirect example.com/https://google.com to http://shortlink.com/s/N9IpzM7J?s=https://google.com?
Because of this post I replace by link shortening service's url to shortlink.com!
If you want to capture full URI, you should use RewriteCond directive.
Apache automatically strips off multiples slashes into a single slash in RewriteRule directive.
RewriteCond %{REQUEST_URI} ^/(.*)$
RewriteRule ^ http://shortlink.com/s/N9IpzM7J?s=%1 [R=301,L]

htaccess rewrite rules with regexp and inifite redirect

I have a hard time to create rewrite rule for a redirect using part of an old URL for WP. Example:
Old URL:
http://www.example.com/news/index.php/2014/11/07/my-blog-post-from-old-site
or
http://www.example.com/news/index.php/2014/11/07/my_blog_post_from_old_site
New URL:
http://www.example.com/2014/11/07/my-blog-post
New URL should to have only dates and first three elements of a permalink after stripping from dashes.
My solution came after combining answers from here https://stackoverflow.com/a/32852444/1090360 and here https://stackoverflow.com/a/1279758/1090360
Somehow part for replacing underscores with dashes creates infinite redirect and a server freezes. If I will remove part with replacing underscores to dashes all the rest works as should.
Here are my .httaccess rules
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#replace underscores with dashes
RewriteRule ^(/news/.*/[^/]*?)_([^/]*?_[^/]*)$ $1-$2 [N]
RewriteRule ^(/news/.*/[^/]*?)_([^/_]*)$ $1-$2 [R=301,L,NC]
#redirect to new URL
RewriteRule ^news/index\.php/([^-]+-[^-]+-[^-]+).* /$1 [R=301,L,NC]
#WP standard stuff
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
I think, this is an expensive way to replace underscores with dashes. But this works at least in my test environment. The first rule replaces dashes one by one. The second rule then removes the prefix from the requested URL.
RewriteBase /
# replace underscores with dashes
RewriteRule ^(news/index.php/.+?)_(.*) $1-$2 [L]
# strip "news/index.php"
RewriteRule ^news/index.php/(.*) /$1 [R=302,L]
I played a bit more with your original approach using the N|next flag and crashed my server too. Looking into the error.log, it seems this infinite loop is created by Apache by adding a "path info postfix", which enlarges the URL with the original URL. And so it keeps replacing underscores with dashes on and on.
You can prevent this path info postfix with another flag DPI|discardpath, which gives the following rule
RewriteRule ^(news/index.php/.+?)_(.*) $1-$2 [N,DPI]
This seems to work too. Although I must admit, I don't really understand this "path info postfix" thing. There's also an entry in Apache's Bugzilla, Bug 38642: mod_rewrite adds path info postfix after a substitution occured
Never test with 301 enabled, see this answer Tips for debugging .htaccess rewrite rules for details.

Remove last / from urls using .htaccess

I would like to remove the last '/' from all urls using a 301 .htaccess redirect. How would I do it? I have tried the following, but it only removes from the first level of directories:
RewriteCond %{REQUEST_URI} ^(/[^/]+)/$
RewriteRule . http://www.mysite.net%1 [L,R=301]
For example, it works for www.mysite.net/first/ but does not work for www.mysite.net/first/second/
Change the [^/]+ to just .+. The ^/ means "match everything except for a slash", so "first" matches but "first/second" doesn't. Also, you don't need a condition here.
RewriteRule ^(.*)/$ http://www.mysite.net/$1 [L,R=301]

Htaccess rewrite index with trailing slash or without

I am currently having a problem with my index url rewrite in my .htaccess file, I know if I use
RewriteRule ^profile/([^/]*)/?$ /profile.php?x=$1 [L]
I would be able to use www.example.com/profile/get or www.example.com/profile/get/ (with or without trailing slash)
But I would like www.example.com/get what I have so far is
RewriteRule ^([^/]*)\/$ /index.php?x=$1 [L]
But if I put a ? before the $ it errors any answers welcome
Making the trailing slash optional will lead to an infinite loop, since [^/]* will match anything that doesn't include a /, ie it would also match index.php?x=get
You can avoid this by making the rule apply conditionally, for example by testing the reqeust URI:
RewriteCond %{REQUEST_URI} !^/index\.php.*
RewriteRule ^([^/]*)\/?$ /index.php?x=$1 [L]
That way the rule can only apply in case the request URI doesn't start with /index.php

exact syntax of RewriteRule

Do I need a slash before or after the /somefolder/(.*) below? I want to redirect everything coming into a folder to another website address. Do I need the RewriteCond in here somewhere also?
Options +FollowSymLinks
RewriteEngine on
RewriteRule somefolder(.*) http://www.differentsite.com$1 [R=301,L]
You don't need a / at the beginning, but a caret ^ will match http://whatever.com/ including the trailing /.
