I've got problem with redirecting old google maps urls to new one. I got new links (after component update), but i want make old ones work.
this is old one
domain.com/index.php?option=com_xmap&sitemap=1&view=xml
this is new one
domain.com/index.php?option=com_xmap&view=xml&tmpl=component&id=1
Please, help me redirect this :)
I think the following redirect would work. It redirects when there is no id= in the query string, and appends id=somenumber to the query string where somenumber is the number behind sitemap.
RewriteCond %{QUERY_STRING} !^(.*&|)id=
RewriteCond %{QUERY_STRING} ^(.*&|)sitemap=([0-9]+)(&.*|)$
RewriteRule ^ %{REQUEST_URI}?id=%2 [QSA,R,L]
A quick rundown of what I used here. %{QUERY_STRING} is a variable, just as %{REQUEST_URI}. A ! before a regex will negate that regex (ala 'doesn't contain'). %2 is replaced with the second capturing group of the last RewriteCond. In this case it will get replaced by whatever is captured by ([0-9]+). The flags are QSA (query string append), R (redirect, default is temporary redirect) and L (if this rule matches, stop rewriting; this doesn't affect the new request that is made). The documentation can be found here.

I have a lot of old urls inbound pointing to incorrect locations, trying to forward to new location. These are going to the root directory so I can't just forward everything.
One way to get a good chunk of them on to the new place is finding ones with a session ID in the query string. It always has 32 characters, preceded by s=
https://www.example.com/some-url-name-1233/?s=ba4a8a734b666b8d43499e5d497599a6
Need to move that to (and drop the session ID)
https://www.example.com/newfolder/some-url-name-1233/
I can't get the .htaccess redirect to match that string.
I've tried multiple ways, most recent being:
RewriteRule ^(.*)s=([^.]{32})$ https://www.example.com/newfolder/$1 [L,R=301]
Any suggestions?
This is an often answere, fully documented issue: you cannot access a request's query string by means of a RewriteRule. You need to use a RewriteCond for that:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^s=[^&]{32}(&|$)
RewriteRule ^ https://www.example.com/newfolder%{REQUEST_URI} [L,R=301,QSD]
I also fixed some other details.
I have a URL
https://example.com/cart?prdid=223
I want to redirect it to
https://example.com/cart/223
using .htaccess
i've tried to use
RewriteEngine on
RewriteCond %{QUERY_STRING} (?:^|&)prdid=(.*)$
RewriteRule ^cart/(.*)$ /cart/$1?prdid=%1 [L,R]
But it does not work.
Rewrite rules have the pattern to match first, then the result you want.
The pattern you need to match is the current URL, which just ends "/cart", with no extra slash or word on the end of it, so instead of cart/(.*)$ you just want cart$
Then the result you want has the ID directly in the URL, not in the query string, and there's nothing for $1 to refer to, only %1 from the RewriteCond line. So instead of /cart/$1?prdid=%1 you just want /cart/%1
Once you've fixed that, the browser will redirect to the new URL. To actually make that URL work, you'll probably need a second rule, without the R flag, to tell Apache what to do when it sees the "pretty" URL. That one will have cart/(.*)$ as the pattern to match, but no condition on the query string, and $1 in the result part, not %1
On Google I have a site that has a bunch of old links to its pages, they are links like this.
/mainpage.cfm?linkId=84&LinkType=mainlink
I want to 301 redirect them with htaccess, but nothing I am trying works.
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/architectural
RewriteRule .* /mainpage.cfm?linkId=84&LinkType=mainlink
Any Ideas, I have tried many varients of this, it seems the problem is the .cfm file.
Your question is a bit fuzzy. You say you want to rewrite from /mainpage.cfm?linkId=84&LinkType=mainlink, but then you also have that as the target of your RewriteRule. So I think some wires are crossed somewhere. Can you please update your question to include "I want to rewrite [this current URL example] to [the URL you wish the first one to end up at]". Also any other considerations that might require a RewriteCond, and any variations in the patterns.
Then we can get your rules/conditions sorted out.
To answer your exact question as asked, your RewriteCond will reject /mainpage.cfm?linkId=84&LinkType=mainlink because that does not match ^/architectural.
However I suspect this is not the question you mean to ask...
in mod_rewrite RewriteRule can only see the directory and file part of the URI and not the query string. So to match the query string you need to use RewriteCond.
e.g.
RewriteCond %{QUERY_STRING} linkId=(\d+)&LinkType=mainlink [NC]
RewiteRule ^mainpage\.cfm newpage.php?linkid=%1 [NC,L]
I have matched the linkId in the RewriteCond which I then refer to by %1 in the RewriteRule as this is the syntax for matching groups in a RewriteCond.
As #AdamCameron points out you don't state where you want to redirect to, but this should give you the tools to resove it.
You could perform the redirect within the ColdFusion page instead. Just add the following line to the top of the mainpage.cfm file (assuming you want every request of that page redirected). You could add some condition logic if you only want to redirect specific linkId and/or LinkType based on the URL parameter.
Again, if you want every request to the mainpage.cfm to redirect just add this to the top of that file (NOTE you need to change the url for the redirected page):
<cflocation url="http://host/architetural" statusCode="301" addtoken="no">
The statusCode attribute was added in ColdFusion 8 - so you must be running that or newer
I am learning how to write regular expressions for .htaccess redirects.
So far I've managed to figure out everything I needed, except for a couple of regular expressions which don't behave as I expected. I am testing my regular expressions using a desktop application, and they work fine there, but not in the .htaccess file.
FYI: The RewriteBase is set to /site/
This is the incoming URL:
/site/view-by-tag/politics/?el_mcal_month=3&el_mcal_year=2009
I want to grab "politics" and redirect to /site/tags/politics/
Here is what I used:
RewriteRule ^view-by-tag/([a-zA-Z\-]+)/([a-zA-Z0-9\-\/\.\_\=\?\&]+) /tags/$1/ [R=301,L]
I added the capture of all the characters after politics because I am having the issue that when there is a ? in the URL the redirect does not work, and I can't figure out why. In the URL given above, if I remove the ? it works fine, but if the ? is in there, nothing happens. Is there a reason for this?
The same thing happens when I try to capture 307 from /site/?option=com_content&view=article&id=307&catid=89&Itemid=55
I used this regular expression, article&id=([0-9]+) /?p=$1 [R=301,L] but again, when there is a ? in the URL it stops the redirect for doing anything.
What is the reason for that?
The .htaccess file in question is on a Wordpress blog (3.4.1)
The point that you've missed is that the rewrite engine splits the URI into two parts: the REQUEST_URI and the QUERY_STRING. The query string part isn't used in the rule match string so there is no point in constructing rule regexp patterns to look for it.
You can probe and pick out parameters from the query string by using rewrite conditions and condition regexps to set %N variables.
By default the query string is appended to the output substitution string unless you have a ?someparam in it -- in which case it is ignored unless you used the [QSA] (query string append) parameter.
The way that you'd pick up the id in /site/?option=com_content&view=article&id=307&catid=89&Itemid=55 is to use something like:
RewriteCond %{QUERY_STRING} \bid=(\d+)
Before the rule and this would set %1 to 307. Read the rewrite documentation for more general discussion of how to do this.
The query string is must be processed separately in a RewriteCond if you need to manipulate it, and should not be matched inside the RewriteRule Instead, just match the request not including the query string, and use QSA to append the query string onto the redirect:
RewriteRule ^view-by-tag/([A-Za-z-]+)/?$ /tags/$1/ [R=301,L,QSA]
# OR, if you don't want the rest of the query string appended, put a `?` onto
# the redirect to replace it with nothing
RewriteRule ^view-by-tag/([A-Za-z-]+)/?$ /tags/$1/? [R=301,L]
Actually, the QSA may not be needed in a R redirect - I think that the default behavior is to pass the query string with the redirect.
If you need to capture 307 from the query string, do it in a RewriteCond and capture in %1:
# Capture the id in %1
RewriteCond %{QUERY_STRING} id=([\d]+)
# Redirect everything to /, pass %1 into p
RewriteRule . /?p=%1 [LR=301,L]
Problem: Visitors open the url website.com/?i=133r534|213213|12312312 but this url isn't valid anymore and they need to be forwarded to website.com/#Videos:133r534|213213|12312312
What I've tried: During the last hours I tried many mod_rewrite (.htaccess) rules with using Query_String, all failed. The last message in this topic shows a solution for this problem, but what would be the rule in my situation.
I'm very curious how you would solve this problem :)!
The following will handle the simple case you show. You'll need to add additional logic if you need to allow for other parameters in the query string or file names before the ?.
RewriteEngine On
RewriteCond %{QUERY_STRING} ^i=(.*)
RewriteRule ^.* /#Video:%1? [NE,R=permanent]
Why is this tricky?
RewriteRule doesn't look at the query string, so you have to use RewriteCond to evaluate the QUERY_STRING variable and capture the part you'll need later (referenced via %1)
the hash character (#) is normally escaped, you must specify the [NE] flag
The trailing ? on the substitution string is required to suppress the original query string
I tested this on Apache 2.2.
