How can step through an Action that is requested from JavaScript during execution?

Question

There is this one action that is requested using javascript during the loading of a page, it takes over 25 seconds to resolve. Looking at the code makes me think there is a scaling issue, but I am wondering if there is any way I can step through the code during the request so I can see what is happening. I try clicking 'debug/start debugging' but it won't launch the proper URL (access to the site is subdomain based), and it will also not find certain dependencies. I am able to browse the site directly via URL locally after mapping a URL via my hosts file to localhost (127...) but the default url that pops up (localhost...) from debug does not work because it is not formatted properly.

Any ideas?

Answer 1

You can attach the debugger to your browser by selecting "Attach to process" under "Debug" menu.

Answer 2

In the past, at least with ASP.NET we have used tracing to debug issues. You will just need to enable it in the webconfig. If you use warn, the messages will show in red and be easier to spot.
