Hi Monks,

I am using AnyEvent::HTTPD / AnyEvent::HTTP::Request. I want to be able to do async IO when a request comes in, and have ability to set the response status, and response content-type, based on the result of that async IO.

However I cannot figure out any way to do this. All the examples I have see all require the content-type specified up-front - and their behavior is that the client is immediately sent response headers (with 200 status and content-type), and then async IO callback is provided, such that only the response body can be asynchronously generated. Example based on AnyEvent::HTTPD::Request doc:

$req->respond ({ content => ['text/plain', sub {
   my ($data_cb) = @_;
   # 200 / text/plain already sent to client by now...
 
   # do async io that eventually calls the call back...
   myPromise()->then(sub{
      $data_cb->("OK"); # Too late to change content-type or status co
+de here..
      $data_cb->();
   })->catch(sub{
      $data_cb->("Failed"); # Or here...
      $data_cb->();
   });
 
} });

Any ideas? Or should I change to a different 'framework'? Thanks!
