Subject RE: HTTPService Response Headers
Date Tue, 05 Feb 2013 21:16:54 GMT
Thanks Rick,

I am in the process of developing API to integrate with the .NET RESTful servicing and there
are two things I am would like to do.
1) On all GET and POST calls to RESTful endpoints attached an "authentication" header with
two name value pairs, i.e. a key and token.
2) I want to be able to handle a 400 Bad Request error (and other 400 errors) and parse through
a JSON payload to allow Flex to determine how to proceed. In the past we have forced a 200
status with a JSON payload but would like to if possible handle 400 errors...

Subject: Re: HTTPService Response Headers


If you are not using a proxy service like BlazeDS... anything other than an HTTP200 is going
to cause your Flex application fits. If you are looking for the notion of a 'successful failure'
where an operation completed (e.g. a partial save) but had errors. You'll need to implement
the semantics of that condition yourself - Flex is relegated to either a result or fault.

If you've considered pushing elements into HTTP headers... remember that custom HTTP request
headers are only supported for POST requests, not for GET requests. 


Additionally, heavy restrictions have been placed on HTTP headers in Flash Player 9.0+ and
may get worse. So... your mileage will depend on which headers you want to touch.


If you have a concrete use-case, we might be able to hammer out an approach that works reliably.
What exactly did you have in mind?
