I asked this question about rewriting old "ugly" links into seo friendly ones.
I need to "extract" some information after the "sharp" symbol in some urls. I've created a regular expression to it but it can't seen to work.
After my question, I created this logic for this url for example, script.php?mode=full&id=23:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /script\.php\?mode=full&id=([0-9]+)\ HTTP/
RewriteRule ^script\.php$ fix_old_urls.php?phpfile=script2&id=%1 [NC,L]
But I'm working in a legacy application, and I need to extract the value after the sharp symbol in some pages, in the example url script.php?mode=full#23:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /script\.php\?mode=list\#([0-9]+)\ HTTP/
RewriteRule ^script\.php$ fix_old_urls.php?phpfile=script&id=%1 [NC,L]
(in fix_old_urls I properly redirect with a 301 code).
The first one works, but not the second. To me it looks like it`s the same logic in both. What am I'm doing wrong?
Anchor information (the part starting with the #) is never actually sent to the server. It's handled completely by the browser, and thus you can't touch it with mod_rewrite (nor can you access it via server-side scripting languages). The only things that can see it are the browser and client-side scripts (like Javascript).

The purpose of this code is to prevent people from accessing a pdf file unless they are accessing the file from another page in https://www.example.com. If they are trying to access the PDF from another site, they are to be redirected to our commercial website https://example2.com. (It is to prevent people who don't have authorized access from downloading a PDF or from copying the URL for the PDF and sharing it with others.)
RewriteEngine On
RewriteCond %{HTTP_HOST}##%{HTTP_REFERER} !^([^#]*)##https?://\1/.*
RewriteRule ^(.*) https://example2.com/ [L,R=301]
The code above worked fine with all browsers until a recent update to IE11 and now it ignores the rewrite condition and always redirects to https://example2.com even if you are linking from https://www.example.com. However it works as it should in Chrome and Edge.
I tried changing the rewrite to what I have below as I am fine hardcoding the URL, but got the same results:
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^https://www.example.com/.*
RewriteRule ^(.*) https://example.com/ [L,R=301]
How do I get this needed functionality to work in IE?
Maybe IE has an old and wrong rewrite rule cached. You could clear cache in IE and try again.
Besides, you could test your rewrite rules in this site. I test with your first code and it says:
This test string is not supported: %{HTTP_HOST}##%{HTTP_REFERER}
I test with your second code and it works. So I think you could clear IE cache and try again with the second code.
For more information, you could refer to this similar thread.
I am taking over an old website, and need to change the domain name.
The current domain is http://www.example.com/folder/ and the new domain is http://example.school.nz
An example of an existing and desired URL is:
Before: http://www.example.com/folder/index.php?page=sport
Desired: http://example.school.nz/about-us/sport
The site is built using CMSMS (http://www.cmsmadesimple.org), so pages and URL's are generated through the CMS, although it's easy enough to export a list of URL's.
Ideally I could set up 301 redirects for the entire site so the user doesn't get 404'd. Any clues to the easiest way to accomplish this?
It depends on how general you want things to be, but this set of rules will do what you asked in your question:
RewriteCond %{HTTP_HOST} .*
RewriteCond %{QUERY_STRING} page=sport
RewriteRule ^folder/index.php http://example.school.nz/about-us/sport? [L,R=301]
Unfortunatly I am forced to use IIS6 for my MVC website. .net 4.0 adds functionality to mimic the stupid hack for getting extensionless urls to work in IIS6. My website is designed to take advantage url rewriting for SEO purposes. The keyword urls that the client wishes to use dictate an elaborate url rewriting scheme.
The problems with Microsofts impelmentation of the feature really comes down to url rewriting and the attempt to match a pattern. I have seen various rules that attempt to strip the dreaded eurl.axd from the url so that the patterns will match. I attempted to use these rules
RewriteRule ^(.)/eurl.axd/[a-f0-9]{32}(.)$ $1$2
or
RewriteRule (.)eurl.axd/. $1
which does work but it also introduces other problems when there are nested redirects. i.e. handling old urls to new ones, etc
what happens is the eurl.axd gets stripped and on the redirect the isapi_filter doesnt get the request which results in an IIS 404 errror.
Tinkering around with the urls, i came up with this possible solution.
RewriteRule ^generators/generator-parallel-capability/([^/])/([^/])$ /generators/htmlcontent/generator-parallel-capability/$1/$2 [NC,L]
it just grabs the eurl.axd portion and rewrites it to the executing url with it appended.
Is there a better way? I have several hundred urls that meet this pattern and it would be nice to have a single rule handle them all.
We used one generic rule on top of the config to cut the /eurl.axd234234
RewriteRule ^(.)/eurl.axd.$ $1 [NC]
this must work for everything but the root.
Using the rewrite rule RewriteRule ^(.)/eurl.axd.$ $1 [NC] results in some unplesant behavior when the url is rewritten more than one time. i.e. from an old url to the new vanity url then to the actual execution url.
Using maps, I was able to produce a pattern that works quite nicely and keeps the .htaccess file from being cluttered.
RewriteCond ${contentmap:$2} >"" [NC]
RewriteRule ([^/]*)/([^/]*)/([^/]*)/([^/]*)$ /$1/${contentmap:$2}/$2/$3/$4 [NC,L]
RewriteCond ${contentmap:$2} >"" [NC]
RewriteRule ([^/]*)/([^/]*)$ /$1/${contentmap:$2}/$2 [NC,L]
The first detects the pattern /controller/some-content/eurl.axd/1234 and rewrites it to /controller/some-controller-action/eurl.axd/1234
the second does the same thing just without the eurl junk at the end. this is for my dev machine running iis 7
Im sure there are better ways and I am certainly open to better suggestions.
I am using rewrite rules with Apache 2 to redirect certain types of pages to HTTPS using vhosts. These are anything that starts with mydomain.com/users. In other words, all pages having to do with users and their information should be on HTTPS. I want to redirect all other pages to HTTP.
What happens now is that when a user goes to a /users page, he is redirected fine to HTTPS. But when he navigates away from the /users area, I can't get the redirect back to HTTP.
I need the rules and conditions to rewrite anything that is NOT /users/* to HTTP. In other words, please help me fill in the blanks:
RewriteCond %{SERVER_PORT} ^443$
RewriteCond %{REQUEST_URI} __blank__
RewriteRule __blank__ http://mydomain.com%{REQUEST_URI} [R=301,L]
In researching this, there are a few things I am trying to avoid. I need a wildcard under /users because I am developing the app and often add pages under users (it's a Rails app).
I understand that it is not easy to do a NOT match with regular expressions. All I am trying to do here is have the bulk of the site run on HTTP except the /users/* pages on HTTPS.
Also, yes I have a valid cert and yes I have verified that the Apache2 rewrite mod works. I can get all URLs rewritten to HTTP no problem. How do I NOT rewrite ones that start with /users in the REQUEST_URI? I think I have actually tried about every answer on this site so far...
There quite a few answers for this sort of questions, -- you just need to search this site a bit. Yes, they do not answer your question 100% straight away (as everyone has slightly different requirements -- like different page name etc) but the whole approach is the same.
In any case -- here how it can be done:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
# don't do anything for images/css/js (leave protocol as is)
RewriteRule \.(gif|jpe?g|png|css|js)$ - [NC,L]
# force https for /users/*
RewriteCond %{HTTPS} =off
RewriteRule ^/users/ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
# force http for all other URLs
RewriteCond %{HTTPS} =on
RewriteCond %{REQUEST_URI} !^/users/
RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
# your other rewrite rules below
These rules need to be placed inside VirtualHost directive BEFORE any other rewrite rules (if such present). If placed elsewhere some small tweaking may be required.
They will
force HTTPS for all resources in /users/,
do nothing for images, css styles and JavaScript files (to be precise, for files with those extensions)
and will force HTTP for all other URLs
IMPORTANT NOTE: It is very likely that these rule will not work for you straight away. That is because modern browser do CACHE 301 redirects from your previous attempts. Therefore I recommend testing it on another browser and change 301 to 302 during testing (302 is not cached) .. or clear all browser caches (maybe even history) and restart browser.
OK...
I have setup things so that when the following page is requested (browser users and servers)
http://www.visualise.ca/?_escaped_fragment_=corona
the website returns the following the content of this (HTML snapshot)
http://www.visualise.ca/corona
Where 'corona' always change, it varies depending on the page the users or servers are requesting. It could also be
http://www.visualise.ca/?_escaped_fragment_=anne-au-cherry
redirecting to
http://www.visualise.ca/anne-au-cherry
Thanks
UPDATE: OK let me be more clear. I use AJAX to load my Wordpress post and they appear like this http://www.visualise.ca/#!/corona when loaded. But it's not crawlable by Google that request to serv them as http://www.visualise.ca/?_escaped_fragment_=corona so I modified Wordpress to do so. Now Google can crawl my page and index its content and accessing the HTML snapshot available at http://www.visualise.ca/corona.
The problem is that when I paste the http://www.visualise.ca/#!/corona link to facebook it seems to read the http://www.visualise.ca/?_escaped_fragment_=corona and is unable to read the content. But when I paste directly the http://www.visualise.ca/?_escaped_fragment_=corona link it works, it reads http://www.visualise.ca/corona (The HTML).
So I thought maybe if I could redirect http://www.visualise.ca/?_escaped_fragment_=corona to http://www.visualise.ca/corona it would solve my problem.
Here is the existing .htaccess file
#--- DH-PHP handlers ---
AddHandler fastcgi-script fcg fcgi fpl
AddHandler php-fastcgi .php
Action php-fastcgi /cgi-bin/dispatch.fcgi
# BEGIN WordPress
<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
The common mistake that a lot of people do is trying to match whole URL including query string. The reality is: when matching URL, the pattern get applied to path part of it and query string has to be matched separately.
Use this rule: it will issue 301 Permanent Redirect from this kind of URL /?_escaped_fragment_=corona to /corona (where corona can be anything).
RewriteCond %{QUERY_STRING} ^_escaped_fragment_=([^&]*)
RewriteRule .* http://%{HTTP_HOST}/%1? [R=301,L]
I guess your question is really "how do I do this kind of redirection?". So the answer is here:
There are three ways that I could think of, each with slight differences.
Doing the redirection server side
This basically means you set redirect headers in your response. In php, you could do this using the header function. It can also do a delayed redirect, in which case you need to worry about the contents of the page.
Doing it using client side using html's "http-equiv" meta tags. This way the page always gets loaded. Example here.
doing it via javascript. Thats you basic document.location.href thing. You need to figure out a way to pass the argument to javascript, or have your JS read it from the address url itself.
Since I've shown you 3 ways of doing this, I really hope that's what you're looking for :P
Update after seeing the comments:
The above methods will cause the URL to change. If you don't want the URL to change, but show the contents of that other page on your original page, you caould either do that using iframes (baaaad), or do the decent thing and set up URL rewriting.
:)
RewriteEngine on
RewriteRule \?_escaped_fragment_=(.*?) /$1 [L,R=301]
is it what are you looking for?
