IIS URL Rewrite Default Language Path - iis

I'm trying to get a rule working whereby the language identifier is in the url path. We want to force the url to the en version if a language is not specified. For example:
www.domain.com/page.aspx should redirect to www.domain.com/en/page.aspx
Here's the rule we have so far, but it keeps ending up in a redirect loop.
<rule name="Default Language" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_URI}" pattern="^/(en|es|ph)/" negate="true" ignoreCase="true" />
</conditions>
<action type="Redirect" url="/en/{R:1}" redirectType="Permanent" />
</rule>
Any ideas where it's going wrong?

Change your rule to:
<rule name="Default Language" stopProcessing="true">
<match url="^en/" negate="true" />
<action type="Redirect" url="/en/{R:0}" redirectType="Permanent" />
</rule>
It will check if the url starts with en/ and if not, it will append en/ in front of the requested path.
You had an infinite redirection because whatever back reference was sent to /en/{R:1}, it was matching (.*) (as it matches anything/everything).

How to add rules in Url redirect in iis 10

I want to write redirect rules in IIS 10. I googled it and spent half of my day figuring out but no luck so I am posting it to get some solution.
https://testing.app.com/apptest should redirect to https://testing.app.com/apptest/account/login
https://testing.app.com/apptest/ should redirect to https://testing.app.com/apptest/account/login
https://test-apptest.testing.app.com/ should redirect to https://test-apptest.testing.app.com/account/login
https://test-apptest.testing.app.com should redirect to https://test-apptest.testing.app.com/account/login
But when user types url https://testing.app.com/apptest/account/login or https://test-apptest.testing.app.com/account/login then it should not redirect anywhere and it should stay as it is.
<rewrite>
<rules>
<rule name="Test1" stopProcessing="true">
<match url="account/login" />
<action type="None" />
</rule>
<rule name="Test2">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="testing.app.com" />
<add input="{REQUEST_URI}" pattern="^/apptest" />
</conditions>
<action type="Redirect" url="https://testing.app.com/apptest/account/login" appendQueryString="false" />
</rule>
</rules>
</rewrite>
We just add an anchor point to the regular expression so that precisely matches the segment ‘/apptest’.
Updated
<system.webServer>
<rewrite>
<rules>
<rule name="MyRule1" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_URI}" pattern="^((/apptest)?)/?$" />
</conditions>
<action type="Redirect" url="https://{http_host}{C:1}/account/login" />
</rule>
</rules>
</rewrite>
</system.webServer>
Explanation
Since the hostname changed and will subsequently be appended in the redirection URL, I replace it with {http_host} server variable to follow it. Besides, {Request_URI} will return the URL path and {C:1} will return either "/apptest" or "". therefore I append it into the redirection URL.
The meaning of every server variable.
https://learn.microsoft.com/en-us/iis/extensions/url-rewrite-module/url-rewrite-module-configuration-reference#accessing-url-parts-from-a-rewrite-rule
Finally, please don’t forget to install the URL Rewrite extension before applying the rules.
https://www.iis.net/downloads/microsoft/url-rewrite
Here is a quick reference of the regular expression from Microsoft documentation.

URL Rewrite rule for a specific domain

URL Rewrite rule for a specific domain
if url is https and have this domain only
https://myServer/SomeApplication/
Redirect it to
https://myServer.mycompany.com/SomeApplication/
Added below didn't work in iis 10, windows server 2019
<rule name="httpsRedirect2" enabled="true" stopProcessing="true">
<match url="^myServer/(.*)" ignoreCase="true"/>
<action type="Redirect" url="https://myServer.mycompany.com/SomeApplication/" appendQueryString="false" />
</rule>
Can someone explain what I've done wrong?
The Rule pattern only can get the URL string as an input, does not include the query string, thus it will not work properly.
Here is an official explanation of how certain parts of the URL string can be accessed from a rewrite rule.
https://learn.microsoft.com/en-us/iis/extensions/url-rewrite-module/url-rewrite-module-configuration-reference#accessing-url-parts-from-a-rewrite-rule
We can match the hostname in the Rule Condition section then apply the Rule Action.
<rule name="Myrule2" enabled="true" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="localhost" />
</conditions>
<action type="Redirect" url="https://vabqia969vm/" />
</rule>
</rules>
</rewrite>

URL Rewriting the path in IIS

I have a site that uses two characters in the URL path to determine the initial language e.g. https://my.company.net/Monitoring/gb displays in the English language. I want to setup a redirect for these two display the full culture code e.g. https://my.company.net/Monitoring/en-GB
This is the rule that I've tried:
<rewrite>
<rules>
<rule name="Monitoring gb rewrite" patternSyntax="ExactMatch" stopProcessing="true">
<match url="https://my.company.net/Monitoring/gb" />
<conditions />
<serverVariables />
<action type="Redirect" url="https://my.company.net/Monitoring/en-GB" appendQueryString="false" />
</rule>
</rules>
</rewrite>
I expected https://my.company.net/Monitoring/gb to redirect to https://my.company.net/Monitoring/en-GB however this rule does not have any effect: the browser URL stays at https://my.company.net/Monitoring/gb.
How can I rectify this?
You could use below url rewrite rule.
<rule name="gb to en-gb redirect" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="ww.sample1.com" />
<add input="{HTTPS}" pattern="on" />
<add input="{REQUEST_URI}" pattern="Monitoring/gb" />
</conditions>
<action type="Redirect" url="https://www.sample1.com/Monitoring/en-GB" />
</rule>
Note: use your hostname instead of the www.sample1.com.
The redirect failure was due to browser caching. The redirect works once the cache is cleared.

IIS rewrite rule not triggered when file-name plus extension is in the url

I am struggling getting an IIS rewrite rule working.
The old urls look like:
https://wwww.testserver.com/package.aspx?TrackingNumber=number
The new web app is expecting the urls in this format:
https://wwww.testserver.com/package/number
Currently I have the following rule setup, which is not working.
<rule name="Rewrite to new Package site" stopProcessing="true">
<match url="^package\.aspx\?TrackingNumber=([_0-9a-z-]+)" />
<action type="Redirect" url="https://www.testserver.com/package/{R:1}" logRewrittenUrl="true" />
</rule>
The interesting part is, if I remove package.aspx\? from the rule, urls like these https://wwww.testserver.com/oldwebsite/TrackingNumber=number are getting matched.
In my test calls I replaced package.aspx with package.html and these urls are not getting matched as well. It looks like IIS ignores urls with filenames in the url.
You could use below url rewrite rule to redirect https://wwww.testserver.com/package.aspx?TrackingNumber=number to https://wwww.testserver.com/package/number:
<rule name="test" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{REQUEST_FILENAME}" pattern="package(.aspx)" />
<add input="{QUERY_STRING}" pattern="TrackingNumber=(.*)" />
</conditions>
<action type="Redirect" url="http://localhost:2568/package/{C:1}" appendQueryString="false" />
</rule>
Note: You could modify hostname as per your requirement.

IIS Rewrite pattern not working

I have a rewrite pattern that I can't get to work.
if someone goes to my site by using this url:
http://example.com/article/page/1?_escaped_fragment_=
I would like my rewrite pattern to match the querystring and then rewrite my path to
/snapshots/snapshot_article_page_1.html
I tried writing a rule like this:
<rule name="Seo rewrite rule" stopProcessing="true">
<match url="(.*)"/>
<conditions>
<add input="{QUERY_STRING}" pattern="(.*)_escaped_fragment_=(.*)" />
</conditions>
<action type="Rewrite" url="/assets/snapshots/snapshot__{REQUEST_URI}.html" appendQueryString="false" />
</rule>
But I just keep getting a 404 error (even though the page exists!). I even tried actually putting in the full URL to the page and it doesn't work, but if I put the URL in the browser, it shows it fine.
It appears I have done it.
The rule to match my example would be this:
<rule name="Seo rewrite rule" stopProcessing="true">
<match url="(.*)"/>
<conditions>
<add input="{QUERY_STRING}" pattern="(.*)_escaped_fragment_=(.*)" />
</conditions>
<action type="Rewrite" url="/assets/snapshots/snapshot__{R:0}.html" appendQueryString="false" />
</rule>
