Automating Browser Workflow with Adobe Air / Flex

It would be great to be able to automate a set of steps that you take frequently within your web browser, and have the information that you're actually after extracted for you automatically. For example, if I were interested in obtaining my financial transactions automatically from my bank each month, a tool with this functionality could be used to download this information automatically in the background.

I dove into this issue a bit the other day using Adobe Air with Flex. I quickly found myself blocked. I couldn't figure out how to intercept the resultant URLRequest that is generated by a user clicking on a link within a rendered HTML / JavaScript page. For example, Imagine I load an initial web page with a form that has a submit button. I fill in information into the form (in the HTMLControl within my flex UI), and click submit. It appears that there's no way to get read access to the URLRequest that is being sent as a result of clicking the submit button. Further, I would like to be able to intercept that request, possibly modify some of the submission parameters, and send it later with a stand-alone URLLoader.

The closest I came to this information was by overriding HTMLHost.updateLocation(), and with the HTMLControl.locationChange event. The most information I was able to find was the new URL being loaded. Even worse, it appears that in both of these cases, I intercept control after the HTTP request has been sent.

It’s looking more and more like this isn’t possible. If it were, some pretty neat tools could be developed.

I wonder, have you managed to find a way around this? This is similar to the issue noted here, which is marked resolved (see the last comment) but I have been unable to get it to work as expected. I wondered if you had succeeded...
