Url rewriting: Redirect one page to another - iis

I want to create a rule to redirect query to a page (which doesn't exist) to another
Example:
http://www.example.com/en/page.asp?id=2&...
to
http://www.example.com/en-US/newpage.asp?id=2&...
I use this rule:
<rule name="Redirect" stopProcessing="true">
<match url="page\.asp\?(.+)$" />
<action type="Rewrite" url="newpage.asp?{R:1}" />
</rule>
But this doesn't work... I got a 404 error...
What is my mistake?
Thanks

URL Rewrite's Rewrite action is only for rewriting the page URL that
gets displayed on the browser but it expects the original page to
exist on the server. For your case, you need a Redirect action.
The regex needs to be changed to reflect "en-US" in the final URL.
Try this code instead:
<rule name="Redirect" stopProcessing="true">
<match url="en/page\.asp\?(.+)$" />
<action type="Redirect" url="en-US/newpage.asp?{R:1}" redirectType="Permanent"/>
</rule>
The permanent redirect helps makes your website SEO (Search Engine Optimized) preventing search engine bots to index the old URL (and hence not splitting page ranks between the 2 URLs).

Need to redirect few URLs via web.config and excluding the rest

We have a requirement for redirecting couple of webpages to different URLs of our website. For instance:
https://old-domain/-->https://new-domain/;
https://old-domain/promotion/campaign-->https://new-domain/;
https://old-domain/about-us-->https://new-domain/about-us/company;
https://old-domain/about-us/awards-and-recognitions-->https://new-domain/about-us/company;
https://old-domain/careers-->https://new-domain/careers/;
https://old-domain/careers/apply-for-a-job-->https://new-domain/careers/;
https://old-domain/claim-status-->https://new-domain/;
https://old-domain/contact-us-->https://new-domain/contact-us;
We need generic rewrite rules for the above, where
we either redirect to the desired destination URLs (manually hard-coding them in the rewrite rules)
or
add a single redirect rule for the first URL and regex expression to skip the rest (since the rest can be managed internally within the CMS but not the first)
I would do it via IIS Rewrite Rules in the web.config (unless the client requires to be able to edit those in the UI)
I would add a rule for each Url (or maybe combine a few where possible)
They could look like this:
<rewrite>
<rules>
<rule name="Redirect old domain" patternSyntax="ECMAScript" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}" pattern="[www.]oldDomain.com$" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://www.newDomain.com/{R:0}" />
</rule>
....
</rules>
</rewrite>
Edit: Updated the rule above so that it will cater for any page on the old domain and will redirect to the same page of the new domain.
Examples:
www.olddomain.com will redirect to www.newdomain.com
www.olddomain.com/about-us will redirect to www.newdomain.com/about-us
Now, you can create the /about-us page in Sitefinity and make it a redirect page and redirect to wherever you want.

IIS URL rewriting has trouble with subcalls

I have two virtual machines. The first one (VM1) is running a web application with an URL like this:
VM1/servicedesk/customer/user/login
The second (VM2) should now redirect to this address without changing the URL and also doesn't allow to redirect to the root / since that is a different web-application. This works relatively easily with this rewrite rule:
<rule name="rewriteAll" stopProcessing="true">
<match url=".*" />
<action type="Rewrite" url="http://VM1/servicedesk/customer/user/login" />
</rule>
It just basically rewrites everything from VM2 to the specific VM1 URL.
The problem I'm facing is that this web-application has many Ajax calls to other addresses on the same VM1.
For example VM1/rest/... or VM1/s/.... I really tried to find each exceptional call and create a rule before this default Rewrite. But since some of them are nested and could be changed this isn't a good approach. So what i need is basically a rewrite without changing the URL what doesn't break the application that does a lot of nested calls.
I found out that i can use the following rule (redirectRest) before the existing rewriteAll rule to redirect subcalls (VM1/rest/..).
<rule name="redirectRest" stopProcessing="true">
<match url="/.*" />
<action type="Redirect" url="http://VM1/{R:0}" />
</rule>
<rule name="rewriteAll" stopProcessing="true">
<match url=".*" />
<action type="Rewrite" url="http://VM1/servicedesk/customer/user/login" />
</rule>
So basically when I call VM1 the second rule applies and I get rewritten to the web-app. The application hosted there will call e.g. VM1/rest what triggers the first rule and redirect the Ajax calls to the root. But I've found out that Ajax calls are not following a redirect like 301.

Point a domain to a URI of an IIS 7 website without changing the domain

I have setup a URL rewrite in IIS 7 for a particular site, that has 2 bindings.
main.mydomain.com
hub.mydomain.com
I have also applied a URL Rewrite Rule as shown below:
match (.*)
and then
under the condition
where {HTTP_HOST} matches ^hub\.mydomain\.com$
301 redirect to
http://main.mydomain.com/hub/home.html
and this works, the purpose was to have hub.mydomain.com direct the user to a URI of http://main.mydomain.com/hub/home.html
I have now been asked to change this so that the hub.mydomain.com remains in the user's browser address but that they are shown the correct /hub/home.html content.
How can this be achieved? I presume that as the name suggests, URL Rewrite is no longer suitable? and if so how else can I do this?
EDIT:
main.mydomain.com still needs to go to the root of the website.
In your question, you state that main.mydomain.com and hub.mydomain.com are binded to a single website.
So if you want the users who hit hub.mydomain.com to be shown with the content from http://main.mydomain.com/hub/home.html, it is equivalent to have them hit hub.mydomain.com and be shwon the content from http://hub.mydomain.com/hub/home.html.
You rule would then go as:
<rule name="hub rewrite">
<match url="^/?$" />
<conditions>
<add input="{HTTP_HOST}" pattern="^hub\.mydomain\.com$" />
</conditions>
<action type="Rewrite" url="hub/home.html" />
</rule>

Rewriting to an URL with hashtags

I'm using IIS URL rewriting module to mask my internal URLs with friendly URLs through rewrite maps and Rewrite rules (not redirection). This is my rewrite map:
<rewriteMap name="HashTest">
<add key="/nohash" value="/nohash.aspx" />
<add key="/hash1" value="/hashtest.aspx#hash1" />
</rewriteMap>
and this is my rewrite rule:
<rule name="Rewrite rule1 for HashTest">
<match url=".*" />
<conditions>
<add input="{HashTest:{REQUEST_URI}}" pattern="(.+)" />
</conditions>
<action type="Rewrite" url="{C:1}" />
</rule>
This is working for URLs with no hashtags, so every time I query www.mysite.com/nohash it shows me content from www.mysite.com/nohash.aspx with our changing the URL on the browser.
Now when I try to rewrite to a URL containing a hashtag I get a 404 error, for instance www.mysite.com/hash1 should just show me content from /hashtest.aspx#hash1 but I just get a 404.
Now if I change my rule action type to Redirect it does make redirection successfully, so I don't know why it doesn't work with rewrite.
I know hashtags are not sent to the server on the request, but it would make sense if my rewrite map was backwards, like <add key="/hashtest.aspx#hash1" value="/hash1" />.
Any insights on why redirection works with hastags but rewrite doesn't?. I'm not married to IIS redirection, if you have another module or approach I can use it's very welcome
The part after the hash sign (officially called the fragment identifier) is a client-side only part of the URL. It's never send to the server. That's why it won't work for rewrite but only for redirects. The rewrite rule will match but IIS will actually try to open a file called hashtest.aspx#hash1 (i.e. a file with the extension .asp#hash1). This file won't be processed as a normal ASP page as the extension is not linked to ASP.NET. And most likely it's content won't even be displayed at all as IIS is by default configured to only allow request for known extensions.

IIS URL Rewriting At Initial Host Request

I am having a problem with an IIS7 Integrated Pipeline URL Rewrite.
For my particular scenario I need to rewrite/redirect part of the initial request as follows.
User enters http://savecontoso.com/files/123456789/somefile.html in the browser address bar.
User is redirected to http://savecontso.com/default.aspx?url= (results of url="default.aspx?url={R:1}")
This currently works as expected only if I create the initial request as such, http://savecontoso.com/default.aspx/files/123456789/somefile.html.
I must note that there is no actual directory of /files/ nor /123456789/ nor any file named somefile.html on the server. I simply need that entire path and filename appended to a query string.
This is my first day working with redirect/rewrite functions using IIS instead of page code behind and I have looked all around learn.iis.net, Google etc to no avail. I understand that rewriting takes place before page requests but for some reason my particular code requires a page request before firing the redirect.
I suspect it is because I am not triggering conditions at the initial request?
<rewrite>
<rules>
<rule name="1" stopProcessing="true">
<match url="(.*)(/files/\d+/.*html$)" />
<action type="Redirect" redirectType="Permanent" url="default.aspx?url={R:1}" />
</rule>
</rules>
</rewrite>
Most likely it does not work because of your match pattern:
the {R:1} will only match (.*) in your pattern, and will never match files/123...
URL in match pattern always starts with no leading slash: should be files/\d+... and not /files/\d+...
Try this one instead (works fine for me):
<rule name="1" stopProcessing="true">
<match url="^files/\d+/.*\.html$" />
<action type="Redirect" url="default.aspx?url={R:0}" redirectType="Permanent" />
</rule>
