Hi,

Is there a way to specify valid URLs that the user can enter and only those URLs will be passed on to wowza? For example for myApp application only the following http request should be reaching Wowza:

http:/domain.com/MyApp/mp4:myStream

People can enter all sorts of stuff:

http:/domain.com/ThyApp

http:/domain.com/mp4:Test

etc. which causes Wowza sometimes to crash.

Thanks!

Hi there.

You can use this API and create some logic to _**String queryStr = httpSession.getQueryStr();**_ to determine if the query is good or not:

You should also look through this guide:
