Hello, I am a fan of Burp! I am using Burp suite Community Edition, and I found a bug in proxy module. Bug is below: In HTTP header, i had a field with name "APP_TYPE", when i intercept the request with burp-proxy, the name "APP_TYPE" is changed into "App_type", so web server does not reply normally. The same thing happend in "APP_BUILD" -> "App_build". Please check your product. I wish Burp-Products becomes the most excellent tool which all over the people in the world love. Thank you.

Thanks for your message. Can you email support@portswigger.net with a few screenshots of the requests and some details about the app you are testing so we can take a closer look, please? Can you also send us screenshots showing the settings you have configured for your proxy listener? Does the app you are testing support HTTP/2?
