IIS URL Rewriting At Initial Host Request - iis

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>

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.

IIS URL Rewrite removing part of path

because a Software provider changed the URL of a Programm hosted in my IIS, I now have many broken links.
The URL used to be
https://example.com/#/subdomain/and/here/some_more
now it is
https://example.com/#/and/here/some_more
They just took away the first part of the path (subdomain)
I thought I could fix my links with an URL Rewrite rule.
I tried this:
<rewrite>
<rules>
<rule name="example" stopProcessing="true">
<match url="(https:\/\/example\.com\/#)(\/subdomain)(\/.*)" ignoreCase="true"/>
<action type="Redirect" url="https://example.com/#{R:3}" appendQueryString="false" />
</rule>
</rules>
</rewrite>
This actually matches in the "Test Pattern" but it doesn't redirect.
I also tried using :
url="{R:1}{R:3}
but still no redirect is happening. I tried with different browsers with no success.
Thanks for the help
The number sign (#) delimits the URI from the fragment identifier. The client should never send this character uncoded. Instead, the client should only send the URI to the server (everything before #). So your client application (web browser) does not send anything after #, which we can see in the URL logged on the server. So what you need to do is to encode this character.

IIS URL Rewriting - Change a querystring key and value into a route

I've recently implemented IIS URL Rewriting on one of my websites. I'm using URL Redirection rather than rewriting for everything. All of my static redirections are working perfectly, however, there's one specific type of dynamic redirection that I can't seem to make work.
I had old URL's that looked like this:
http://example.com/?tag=mytag
I'd like this to be redirected to the new URL format of:
http://example.com/tag/mytag
For these URL's the querystring key (tag) is known and fixed, however, the querystring value ("mytag" in the example above) is entirely dynamic and unknown in advance (so I don't believe it's therefore possible to use IIS Rewrite Maps).
Is is possible to add an IIS Rewrite rule that performs this kind of redirection for all possible querystring values that may be supplied?
Yes, the guts of the solution are below. Whats going on is...
1st condition means only apply this rule to the top level of the site. So http://example.com/?tag=mytag will redirect, whereas http://example.com/foobar/?tag=mytag wouldnt.
2nd condition is the magic. It only runs if a query param called tag exists, and the (.*) is a regex to grab the value for use in the new URL.
The action uses the value you grabbed in the 2nd condition referenced as {C:1}. appendQueryString does exactly what it says - set as appropriate. redirectType should be left as Temporary (HTTP response code 307) until your happy, then change it to Permanent (HTTP response code 301). Once you send a 301 response the client(/search engine) will potentially cache the response and not re-request from the server causing problems if you make a mistake.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Redirect based on tag query value">
<conditions>
<add input="{REQUEST_URI}" pattern="$" />
<add input="{QUERY_STRING}" pattern="tag=(.*)" />
</conditions>
<action type="Redirect" url="tag/{C:1}/" appendQueryString="false" redirectType="Temporary" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

Url rewriting: Redirect one page to another

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).

Problem with URL rewrite on IIS 7.5

I'm trying to use the URL Rewrite module for IIS 7.5 to redirect all HTTP requests to HTTPS for my ASP.NET website. The site works fine at the moment but forces the user to type the https:// in the address bar.
I followed the instructions in this article. Everything seems to be fine: I've tried putting the rule in the web.config and it shows up in the UI as it should; I've also done the reverse and can see the changes in the web.config when I use the UI to add the rule. I have RequireSSL unchecked for the site. Unfortunately I still just get a 404 when I try to hit the site via http://.
I've tried a few different action urls including {HTTP_HOST}/{R:1} and the one shown below.. nothing works.
<system.webServer>
<rewrite>
<rules>
<rule name="Redirect to https" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}"
redirectType="SeeOther" />
</rule>
</rules>
</rewrite>
</system.webServer>
I'm fairly new to this and pretty frustrated at this point. Seems like this should be a lot easier. Any advice would be appreciated, thanks..
Reposting from ServerFault as it's been sitting unanswered for a while.
HTTP Error 404. The requested resource is not found
Do you actually have binding for HTTP 80 port? Sounds like you do not have it (only HTTPS).
The reason I'm asking is the quoted text is the exact message that I would see if I request unknown to IIS domain (when there is no catch-all defined) or domain is not bound to the requested port.
