I have been struggling with the same issue for a while now and I could not find an good answer yet. I'm using rack-rewrite to add some url rewrite rules to my app's middleware stack.
I have the following rule:
r301 %r{^/([^(docs|help|legal|login|account|apps)])(.+)/$}, '$1'
Which is not working properly or as I would expect it. I have tried one of my previous question's answer, but neither that works, it actually generates an event more weird behaviour (it redirects to an url without the domain name, just to the path).
What I am trying to do is:
if user requests http://example.com/ or http://example.com/random-path/ I need the rewrite rule to strip the slash, thus the examples would become http://example.com respectively http://example.com/random-path;
if the requested paths matches any of the paths in the list docs|help|legal|login|account|apps, do not strip the slash at the end of the path if exists, but add a slash if it's not there
I tried with two rules, one that ignores the listed paths above and strips slashes and one that adds the slash if it hits something from the list and the slash after the path is not there:
r301 %r{^/([^(docs|help|legal|login|account|apps)])(.+)/$}, '/$1'
r301 %r{^/([(docs|help|legal|login|account|apps)])(.+)/$}, '/$1/'
How could I write a rule that would do that, or two rules, because what I tried it did not work?
You can do that like so:
r301 %r{^/((?!docs|help|legal|login|account|apps).+)/$}, '/$1'
r301 %r{^/((?=docs|help|legal|login|account|apps).+[^/])$}, '/$1/'

and some documentation on lookahead and lookbehind

I'm using IIS7.5 and have a rule for rewriting a URL...
The rule is:
^trade/new_products/page([^/]+)/?.*$
But, this is only working when I don't include a slash - e.g.
http://www.website.com/trade/new_products/page1
I'd like it to also work with
http://www.toppstiles.co.uk/trade/new_products/page1/
Can I do this or do I need a separate rule?
This group ([^/]+) is catching everything but slash. If your page is only numeric you can try this one:
^trade/new_products/page([0-9]+)/?.*$
If not, you can use the non greedy modifier on the multiplier(+?):
^trade/new_products/page([^/]+?)/?.*$
Sorry - the rule was working as expected - it was another issue that was causing my problem!
I need to identified urls that are either "/fr/" or "/en/". (and only these two)
I'm looking for the good regular expression.
Of course it works if I write "/../", but it's too large.
Best I could find is "/[fe][rn]/" but it also take /fn/ and /er/.
Simply use a pipe in a group :
/(fr|en)/?
Edit: added the optional trailing slash
I need to rewrite some url on my site
http://wwww.example.com/poem.php?s=to-sally
to
http://wwww.example.com/poems/to-sally
I wrote this rule but doesnt work
RewriteRule ^poems/([a-zA-Z0-9-]+)$ poem.php?s=$1
A couple things:
Make sure you have RewirteEngine On, and actually have the mod_rewrite module loaded and running
I believe the paths being matched against start with /, but your rule dictates that the first character is p. Try replacing your match expression with ^/poems/([a-zA-Z0-9-]+)$ and see if that does the trick.
I cannot wrap my head around URL rewriting. What I want to do seems very simple but I am having problems getting the results I want.
I would like allow users to type www.mysite.com/search/real with an optional / at the end. This would take them to www.mysite.com/content/search_real_property.asp
That's it. Here is the rule I have right now. The problem with this is it will keep stacking.
RewriteRule ^(search) content/search_real_property.asp
So this would work /search/real but so would search/real/search/real/search/real/
and others.
Assuming there are no other issues, you've turned the rewrite engine on (RewriteEngine On) and that you're either adding the rewrite in httpd-vhosts.conf or an .htaccess file in the root of the web tree (so that any path issues are resolved)... then the issue is merely one of Regular Expression pattern matching. Though I'm a bit perplexed by ASP running on what appears to be an Apache server (assuming this IS mod rewrite we're talking about).
So, all you really want is to terminate the match - something like:
RewriteEngine On
RewriteRule ^search/real/?$ /content/search_real_property.asp
That will fix it to /search/real (with or without a trailing slash, the ? means match the preceding character 0 or 1 times) to /content/search_real_property.asp. As the $ sign denotes the line terminator (EOL effectively) there must be nothing after "real" (except perhaps that 1 forward slash).
For greater flexibility you might want to look at what you can actually do with regular expressions, for instance...
RewriteEngine On
RewriteRule ^search/([^/]*)/?$ /content/search_real_property.asp?query=$1
Which would allow you to take any string and pass it in the address bar as a variable called query (Request.QueryString('query') IIRC).

I am using below rule to read the URL like
URL:
http://www.example.com/blog/sampe-post-title/10004/
RULE:
RewriteRule (.*)/(.*)/([0-9]+)/$ $1/details.asp?mod_id=$3 [NS,I]
Everything was fine untill I discovered that links coming via feedburner are not working anymore. Because feedburner adds some extra parameter to URL for stats/tracking etc.
For example www.example.com/blog/sampe-post-title/10004/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed:+somesite+(my+feed)
My rewrite URL doesn't recognizes the above URL anymore. Any idea how to deal with it?
Try adding a rule for the feedburner URLs:
RewriteRule (.*)/(.*)/([0-9]+)/\?(.*)$ $1/details.asp?mod_id=$3&$4 [NS,I]
I added an extra RegEx group at the end to capture everything after the question mark and place it after mod_id. You could probably combine this with your other URL if you only wanted to have one rule for some reason, but you might as well just have two.
Try the QSA flag to get the original requested URL query automatically appended to the new one.
I managed to figure out the answer on my own: just replace the ending $ with .* That's it!
Here is the modified rule:
RewriteRule (.*)/(.*)/([0-9]+)/.* $1/details.asp?mod_id=$3 [NS,I]
