in existing production we have URL structure as follows https://mainsite.com/subsite

Now the sub site URL structure changed as follows https://mainsite.com/newsubsite/subsite2

We want to redirect old sub site landing page and all the inner pages to redirect to new url structure I.e., when user browse https://mainsite.com/subsite it should redirect to https://mainsite.com/newsubsite/subsite2

And when user browse https://mainsite.com/subsite/innerpage it should redirect to https://mainsite.com/newsubsite/subsite2/innerpage

The inner page name don't have any name changes. Just need to replace "subsite" with "newsubsite/subsite2"

Edit: one more scenario need to handle. Some times language code e.g.: "en" will come in the URL as like below https://mainsite.com/en/subsite

In this case it need to redirect to https://mainsite.com/en/newsubsite/subsite2

Same for inner pages as well

Any body help me to create a generic rewrite rule to do this job.

A simple rule like that will do the trick:

<rule name="subsite rule" stopProcessing="true">
    <match url="^([a-z]{2}(\-[a-z]{2})?/)?subsite(/.*){0,1}$" />
    <action type="Redirect" url="/{R:1}newsubsite/subsite2{R:3}" appendQueryString="true" />
</rule>

Remember to recycle app pool after you edit your config - simple site restart related to config change is not enough usually.

Match is for the urls starting (optionally with language code either 2 letters like en or 4 letters with hyphen like en-us), and then with subsite and then either nothing after it or urls starting with subsite/, e.g.

https://mainsite.com/subsite
https://mainsite.com/subsite/
https://mainsite.com/subsite/subfolder
https://mainsite.com/subsite/sub/sub/sub
https://mainsite.com/en/subsite
https://mainsite.com/en-us/subsite/
https://mainsite.com/en-es/subsite/subfolder
https://mainsite.com/en/subsite/sub/sub/sub

Whatever comes after subsite will be added to resulting url after /newsubsite/subsite2.

appendQueryString="true" makes sure that if there is query string, it will be included in the new url as well.

You can redirect your existing production we have URL to sub site URL as below

<rule name="ms1" stopProcessing="true"> 
<match url="^subsite/?$" /> 
<conditions logicalGrouping="MatchAny"> <add input="{HTTP_HOST}" 
pattern="^(mainsite.com|www.mainsite.com)$" /> </conditions> 
<action type="Redirect" url="https://mainsite.com/newsubsite/subsite2" /> </rule>

I tested this with my instance URL and it is working as expected.

Hope this helps.
