Setup a redirection in IIS with parameters carried over

Question

If I have a website like the following:

https://xxx/section1/
https://xxx/section2/
https://xxx/section3/

But users may also access the URLs with parameters:

https://xxx/section1/&p=1494943

I'm going to create a seperate site in IIS6 which will redirect any HTTP requests to the HTTPS website:

request: http://xxx/
redirected to: https://xxx/

And in the same sense:

request: http://xxx/section2/&p=1474724
redirected to: https://xxx/section2/&p=1474724

My question is, how can I ensure they are redirected to the correct section and still carry over the parameters?

Thank you very much for your help.

Solution

If you set the $Q flag in the redirect URL, the request/query parameters should be included in the redirect from the original. If you don't want the question mark to be included in the redirect URl, then use $P instead.

examples:
using $Q:
Original URL: http://startingURL?param1=1&param2=2
Redirect URL: https://newURL$Q
Resulting URL: https://newURL?param1=1&param2=2

using $P:
Original URL: http://startingURL?param1=1&param2=2
Redirect URL: https://newURL$P
Resulting URL: https://newURLparam1=1&param2=2
