I'm running a legacy website which has a tonne of 301 redirects on it. In an effort to make my life simpler, I switched them from doing manual 301 redirects in IIS to using the url rewriting module and a rewrite map, which I can generate from the database.
Unfortunately I've now hit a snag, in that some of their urls come with querystrings (from Google's adwords), and these invariably 404 (because they don't match the urls in my rewrite map).
Is there a way around this, or do I have to go back to manually doing the 301s?
For the record: we're using IIS7
Code samples:
url: http://mydomain.com/widgets/?gclid=[google code]
Rewrite Rule:
<rule name="Rewrite rule1 for News301Redirects" stopProcessing="false">
<match url=".*" />
<conditions>
<add input="{News301Redirects:{REQUEST_URI}}" pattern="(.+)" />
</conditions>
<action type="Redirect" redirectType="Permanent" url="{C:1}" appendQueryString="false" />
</rule>
Map Line:
<add key="/widgets/" value="/widgets.asp" />
Well, the answer proved to be depressingly simple - just an absolute pig to find.
Instead of using REQUEST_URI (which gets the whole requested URL, including the querystring) I've switched to using URL (which just gets the URL without the querystring) and that seems to have utterly resolved my problems.

I'm fairly new to url rewrite and trying to figure this thing out.
I have a website with the following structure:
http://localhost/virtualdirectory1/somepage.aspx?parameter1=x
http://localhost/virtualdirectory2/
Now I added a rule for a redirect (inbound rule):
matches pattern (regex) ^$ to make sure that if anybody goes to http://localhost that they are redirected to http://localhost/virtualdirectory1/somepage.aspx?parameter1=x
This also works fine for http://localhost/?paramter1=x which gets redirected properly.
This still allows me to approach http://localhost/virtualdirectory2/ directly.
However if the user goes to http://localhost/somepage.aspx?paramter1=x they are not redirected to the virtualdirectory1
Could give me some tips on how that can be done?
Thanks!
Is this rule achieve your requirement? It will redirect both http://localhost and http://localhost/somepage.aspx?paramter1=x but it won't redirect http://localhost/.
<rule name="redirect" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{URL}" pattern="^(/somepage\.aspx)?$" />
</conditions>
<action type="Redirect" url="virtualdirectory1/somepage.aspx?parameter1=x" appendQueryString="false" redirectType="Temporary" />
</rule>
I need to redirect URLs of the form:
http://server1.name.here/path1/path2/?num=123456
to:
http://server2.name.here/path3/path2/?num=123456
using the IIS URL Rewrite Module 2.0 on IIS 8.5. I've used a DNS alias to handle the server name redirection.
I've been using the user interface to configure the path rewrite but despite trying several variations and extensive research I cannot get my rewrite to work, which is slightly embarrassing as I feel this should be a simple rewrite. The web.config produced by the URL rewite user interface is:
<rewrite>
<rules>
<rule name="path rewrite" patternSyntax="ECMAScript" stopProcessing="false">
<match url="path1/path2/" ignoreCase="true" />
<conditions>
<add input="{QUERY_STRING}" pattern="num=[0-9]+" />
</conditions>
<action type="Rewrite" url="path3/path2/" appendQueryString="true" logRewrittenUrl="true" />
</rule>
</rules>
</rewrite>
When I try to open server1.name.here/path1/path2/?num=123456 I get a "403 - Forbidden: Access is denied." and the logs show no evidence that my URL is being rewritten or even flagged by the rewrite rule.
I'm sure I'm missing something obvious, can anyone enlighten me as to what I've got wrong?
Many Thanks Eden
I've just started using iis rewrite rules for the first time and I'm struggling with what I imagine is an easy rule.
Basically, I wish to use this rule
<rule name="redirect">
<match url="^(one$|two$|three$)" />
<action type="Redirect" url="{HTTP_HOST}{REQUEST_URI}" />
</rule>
But have the redirect {HTTP_HOST} string minus the extension [.co.uk / .com etc.].
e.g.
bigsite.co.uk/one
would redirect to:
bigsite.co.uk/bigsite/one
How does one go about this - for I can only find Tolower / UrlEncode / UrlDecode string manipulators?
[Ultimately, I would also like to then use a rewrite rule to hide the fact that the redirect has occurred, i.e. the address would remain as bigsite.co.uk/one after the redirect.]
Well I eventually came up with this (hope it may help someone):
<rule name="redirect">
<match url="^(one$|two$|three$)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^(www.)?(.*).co.uk" />
</conditions>
<action type="Redirect" url="{C:2}{REQUEST_URI}" />
</rule>
...not sure if there is a better way, but it works perfectly for me - thanks all, PP
I'm rebuilding a site using iis urlrewriting on both static and dynamic pages. The redirects are all working well. The rewrite module is working perfectly.
Since the site structure is changing, I need to be able to redirect "old" defunct urls to new pages. So, for example, www.sitename.com/research.asp needs to be redirected to www.sitename.com/news
I've followed the instructions to set up a rule using a rewrite map and placed the rule near the top of my webconfig file (just under the CanonicalHostNameRule). But whatever permutations I've tried in the rule, I just can get it to work. The redirects don't happen - I just get a 404 for the (non-existent) .asp page. The map just seems to be getting ignored entirely. Just to re-iterate, all my other rules are working fine.
I've tried turning off all other rules and just working with this one, but no luck. Equally, I've trawled this forum and others for suggestions (using REQUEST_URI rather than Filename, restarting IIS, recycling App. Pools, etc etc), but nothing seems to work. The "Redirect" url="{C:1}" just sends me back to the old asp page I'm trying to get redirected away from, if that makes sense. Nothing in FailedRequestTracing seems to help, either.
Am I missing something very obvious here?
The Rule:
<rule name="Redirect Rule" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAny" trackAllCaptures="false">
<add input="{StaticRedirects:{REQUEST_FILENAME}}" pattern="(.+)" />
</conditions>
<action type="Redirect" url="{C:1}" appendQueryString="false" redirectType="Permanent" />
</rule>
The Map:
<rewriteMaps>
<rewriteMap name="StaticRedirects">
<add key="research.asp" value="news" />
<add key="blog.asp" value="news" />
<add key="mentors.asp" value="interviews" />
<add key="regulars.asp" value="opinion" />
</rewriteMap>
</rewriteMaps>
NB - there are lots of other static redirects to add to this once it actually works, which is why I wanted to use a map.
I'm just trying to get some code running on ISS that has been running on Apache for a long time.
A particular mod_rewrite rule is proving difficult to get working.
In Apache I've used:
RewriteRule ^media/(js|css|img|font)/(.+)\.(\d+)\.(js|css|png|jpg|gif)$ /media/$1/$2.$4
[L]
To turn a URL like /media/css/style.1367406756.css into /media/css/style.css, letting me put timestamps in the files to avoid caching issues.
In my web.config file I've added:
<rule name="Cache bust assets" stopProcessing="true">
<match url="^(.*)$"/>
<conditions>
<add input="{URL}" pattern="^media/(js|css|img|font)/(.+)\.(\d+)\.(js|css|png|jpg|gif)$"/>
</conditions>
<action type="Rewrite" url="/media/{R:1}/{R:2}.{R:4}" appendQueryString="true" />
</rule>
Which, looks like it should work. (It's alongside another rule, which works fine, so it's not that the server isn't parsing it or anything).
I don't get any errors, other than visiting /media/css/style.1367406756.css gives me a 404 error.
How Can I make this work?
You use {R:N} back references in your action when you should use {C:N} since the information comes from the conditions. See Using Back-references in Rewrite Rules for more information.
You can see this error if you open the iismanager console:
To get your rule to work you have 2 solutions.
First you can change your action to (using {C:N}):
<action type="Rewrite" url="/media/{C:1}/{C:2}.{C:4}" appendQueryString="true" />
Or (and I do think it is a better solution), you can use the Import mod_rewrite Rules tool.
In the iismanager console, click on Import Rules... (on the right tab) and paste your apache rule:
This will create for you the following rule:
<rule name="Imported Rule 1" stopProcessing="true">
<match url="^media/(js|css|img|font)/(.+)\.(\d+)\.(js|css|png|jpg|gif)$" ignoreCase="false" />
<action type="Rewrite" url="/media/{R:1}/{R:2}.{R:4}" />
</rule>
