In Application Request Routing, the webpages may not show updates for up to a minute. This behavior is by design.
Details
During the development of a website, we must constantly refresh the page we are working on to see our updates. If we cannot see new code updates, our visitors or clients could see broken pages when they visit our site, which is unacceptable.

Deploying an ARR (Application Request Routing) server with many child servers makes it suitable to cache pages to make things work a lot more efficiently for our clients and our servers.
Recreate Issue
When your updates are not displaying on the page but files are updated on the server, this can be caused by many factors.
We are working with an ARR server, which has its server farm using a Caching Server within IIS, which renews every 60 seconds.
Resolve Issue
Open IIS
Choose the ARR Server Node and expand it.
Expand [Server Farms]
Click on [Farm Name]
Click and open [Caching]
In the section [Memory cache duration (seconds): 60]
Change the seconds to something smaller while developing; once finished, reset this back to 60 or higher.

If you do not want to cache, uncheck [Enable disk cache]
It is strongly advised to this on, as it helps deliver pages faster to clients and relieves some of the stress from the server.
