Hi, I have a web application where there is a section that is redirecting to another web application that is working through Azure application proxy. The thing is when I click on the section of the first web, it redirects to Azure login, and when I login it redirects correctly to the second web application (the one working through the proxy) but the query string is gone, for example:
- The URL should be "https://example.com/example?id=1234" after the redirect, but instead the url is "https://example.com", and is landing on the home page instead of the desired URL.
Can anyone help me with this problem?
Thank you so much in advance!

- Open the Azure portal and navigate to your Application Proxy instance.
- Select the "Application Proxy" option from the left-hand menu.
- Select the application that you want to configure.
- Under the "Pre-Authentication" section, select the "Change" button next to "Additional settings".
- In the "Additional settings" dialog box, select the "Pass query string parameters" option.
- Save your changes and test the application again.
Please let me know the results and I can help you further.
Best,
James

When I enter in Application proxy options I can't configure an app. The configuration you are talking about is accessed via the following button?
Also I am trying to see more options on the application proxy configuration (Inside the Enterprise Applications section) and the only options I can see to configure Pre-Authentication is the following:
Thank you!

Best,

When populating the Internal URL within the proxy setting, it doesn't allow me and says "Url cannot have query string.". I am an administrator and not a developer and not sure how to go about this issue. Any help is greatly appriciated.
