I am trying to write a Rewriterule which takes a domain from a URL of the format
https://www.example.com/sample?TARGET=https%3A%2F%2Fwww.example.com%2Fexample%2Fhelp%3Fparam%3D1.
If the TARGET parameter is present I need to redirect the user to the value inside the TARGET query parameter. My rewrite rule is below:
RewriteCond %{QUERY_STRING} TARGET=([-a-zA-Z0-9_+]+)
RewriteRule ^(.*)$ %1? [R=302,L]
This does not work because of two problems:
%1? in the rewrite rule causes the rewrite to append the value of the TARGET query string to the existing domain.
The value of %1 only contains https rather than https%3A%2F%2Fwww.example.com%2Fexample%2Fhelp%3Fparam%3D1.
I understand that this might not be the best way to go ahead with this, and I am open to suggestions.
You can use this rule instead:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^TARGET=(.+)$ [NC]
RewriteRule ^ %1? [NE,R=302,L]
Important to use .+ in regex to be able to capture all characters of the URL specified in TARGET parameter.
This will redirect:
http://yourdomain.com/?TARGET=https://www.example.com/example/help?param=1 to
https://www.example.com/example/help?param=1

I have a URL that is in the format http://www.example.com/?s=query
I want to redirect this URL to http://www.example.com/search/query
I have the following .htaccess but I wanted to check if there is anything wrong with this. My RewriteRule looks a little wonky and I don't know if it will cause problems for other URLs.
RewriteEngine on
RewriteCond %{QUERY_STRING} ^s=(.*)$ [NC]
RewriteRule ^$ /search/%1? [NC,L,R]
I ran a test Here and it seems to redirect to the correct URL.
RewriteCond %{QUERY_STRING} ^s=(.*)$ [NC]
RewriteRule ^$ /search/%1? [NC,L,R]
You will likely need the NE (noescape) flag on the RewriteRule directive if you are receiving a %-encoded URL parameter value, otherwise the target URL will be doubly-encoded. The QUERY_STRING server variable is not decoded by Apache.
It also depends on how you are rewriting /search/query back to /?s=query (or presumably more like /index.php?s=query?) - presumably you are already doing this later in the config? You only want this redirect to apply to direct requests and not rewritten requests (otherwise you'll get a redirect loop). An easy way to ensure this is to check that the REDIRECT_STATUS env var is empty.
For example:
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^s=(.*) [NC]
RewriteRule ^$ /search/%1 [NE,QSD,R,L]
Other points:
The QSD flag would be preferable (on Apache 2.4) to appending ? to the end of the susbtitution string in order to remove the query string.
The regex ^s=(.*) (the trailing $ was superfluous) does assume that s is the only URL parameter at the start of the query string. As it stands, everything is assumed to be part of this value. eg. s=foo&bar=1 will result in /search/foo&bar=1.
The NC flag on the RewriteRule directive is superfluous.
Should you also be checking for /index.php?s=<query>? (Or whatever file/DirectoryIndex is handling the request.)
I have a query string URL: http://localhost/cgi-bin/qgis_mapserv.fcgi?map=/home/qgis/project/map.qgs. I want to hind the map.qgs path in the variable MAP. Besides the map variable, there are some variables (version, request, service, etc).
Here is what I need:
RewriteRule:
Pattern: ^cgi-bin/qgis_mapserv.fcgi?map=map.qgs&(.)$
Substitution: ^cgi-bin/qgis_mapserv.fcgi?map=/home/qgis/project/map.qgs&(.)$
Find bellow my unsuccessful attempt:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/cgi-bin/qgis_mapserv.fcgi$
RewriteCond %{QUERY_STRING} ^map=([A-Za-z0-9.-_]+)$
RewriteRule ^cgi-bin/qgis_mapserv.fcgi?(.*)$ cgi-bin/qgis_mapserv.fcgi?$1
Note: The map variable can show up in the pattern uRL anywhere among the other variables.
I wonder what I am missing on the code above
You are almost there.
The reason why your rule isn't working is because you can't test queryString in pattern of a RewriteRule.
You need to change your rule's pattern to
RewriteRule ^cgi-bin/qgis_mapserv.fcgi$
With this change your htaccess rules will look like :
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/cgi-bin/qgis_mapserv.fcgi$
RewriteCond %{QUERY_STRING} ^map=([A-Za-z0-9./-_]+)/map.qgs$
RewriteRule ^/?cgi-bin/qgis_mapserv.fcgi$ /cgi-bin/qgis_mapserv.fcgi?%1 [R,L]
I've got an application that has been migrated to a newer platform. The tasks are similar and I'd like to redirect a GET parameter to a directory. For example
http://gallery/index.php?gal=ABC => http://photos/gal/ABC
and
http://gallery/?gal=DEF => http://photos/gal/DEF
and the anything that doesn't get caught redirect it to http://photos
I've tried
RewriteEngine on
RewriteCond %{QUERY_STRING} ^(\w+)=(\w+)$
RewriteRule ^(/index.php)$ /%1/%2?
However all I get is a 404 and no redirection. Similarly, I've tried
RedirectMatch ^/index\.php\?=gal(.*) http://photos/gal/$1
but I'm having trouble escaping the ? in the original URL.
What would be the proper way of going about this?
Create a .htaccess file and insert the following code:
RewriteCond %{QUERY_STRING} ^(.+)=(.+)$
RewriteRule ^index.php$ http://photos %1/%2? [L,NC,R=301]
Your order is reversed. Rewrite it in front of you
RewriteRule /(.+)\/(.+) index.php?$1=$2
The question is old but might be still relevant for others, so I suggest a slightly different general approach:
RewriteEngine On
RewriteCond %{QUERY_STRING} key=([0-9a-zA-Z]+) [NC]
RewriteRule (.*) /%1? [R=302,L]
Notes:
QUERY_STRING in the condition checks for a param name "key" and catches it's value
The rewrite rule adds the param value as directory using %1. Note the ? removes the original query part from end result
I am setting up Query string redirect :
expo.com/en/general/campaigns/on-second-thought.html?slide=ost-2016-tank to
expo.com/en/general/campaigns/on-second-thought/ost-2016-tank.html
RewriteCond %{HTTP_HOST} ^(.*)expo\.com
RewriteCond %{QUERY_STRING} slide=ost-2016-tank
RewriteRule ^/en/general/campaigns/on-second-thought.html?$ http://www.expo.com/en/general/campaigns/on-second-thought/ost-2016-tank.html [R=301,L,NC]
redirect happening but its appending ?slide=ost-2016-tank like below
http://www.expo.com/en/general/campaigns/on-second-thought/ost-2016-tank.html?slide=ost-2016-tank
slide=ost-2016-tank parameter is added to redirected page
Since your rule does not define a new query string, the default behavior of Apache is to copy the old query string to the new URL. To get rid of it, append a ? to the address you rewrite/redirect to:
RewriteRule ^/en/general/campaigns/on-second-thought\.html?$ http://www.expo.com/en/general/campaigns/on-second-thought/ost-2016-tank.html? [R=301,L,NC]
Or, for Apache >= 2.4, you can also use the flag QSD (Query String Discard):
RewriteRule ^/en/general/campaigns/on-second-thought\.html?$ http://www.expo.com/en/general/campaigns/on-second-thought/ost-2016-tank.html [R=301,L,NC,QSD]
Simply add a blank query string when redirecting:
RewriteCond %{HTTP_HOST} ^(.*)expo\.com
RewriteCond %{QUERY_STRING} ^slide=(ost-2016-tank)$
RewriteRule ^(/?en/general/campaigns/on-second-thought)\.(html)$ $1/%1.$2? [R=301,L,NC]
No need to mention http://expo.com again when redirecting. It'll automatically redirect to the same hostname because of R flag. No need to repeat same strings over and over. Using match groups and referencing them later works.
Your pattern had .html?$ in it, which actually means that it'll match .html as well as .htm. You do not receive query strings in RewriteRule context.
I have a PHP site which replaces an ASP site, so the path structure is different.
In the URLs, I need to match http://apache.site/Cartv3/Details.asp & redirect to another location. What is the correct syntax to match that URL fragment?
I've already tried
RewriteCond %{REQUEST_URI} CartV3/results1.asp?Category=60
RewriteRule ^(.*)$ home-study/A-Levels/1/page-1 [R=301,L]
and
RewriteRule ^CartV3/Details\.asp?ProductID=1004 home-study/A-Levels/1/page-1 [R=301,L]
You meed to read more about mod_rewrite. Remember RewriteRule doesn't match query string. You attempt needs to be rewritten as:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^Category=60$ [NC]
RewriteRule ^CartV3/results1\.asp$ /home-study/A-Levels/1/page-1? [R=302,L,NC]
Once you verify it is working fine, replace R=302 to R=301. Avoid using R=301 (Permanent Redirect) while testing your mod_rewrite rules.
PS: ? after page-1 is a special mod_rewrite syntax to strip original query string. If you want to keep original query string in rewritten URL then take out ? in the end.
The problem here is that you are trying to match the query string, which has to be done by a separate RewriteCond. If you want the match specifically "Category=60", then you can add it as a Condition:
RewriteCond %{QUERY_STRING} Category=60
RewriteCond %{REQUEST_URI} /CartV3/results1.asp
RewriteRule .* home-study/A-Levels/1/page-1?
This will match http://example.com/CartV3/results1.asp?Category=60 and redirect. The ? at the end of the rule stops "?Category=60" being to the resulting URI.
If you don't care about the value in the query string, then you can remove the first condition.
