ios - How to send two reponses to a GCDWebServer request

Question

I'm using GCDWebServer's addDefaultHandlerForMethod:@"GET" and sending an NSData response via GCDWebServerDataResponse responseWithData:contentType:@"application/octet-stream"

The user's browser receives a file which it saves in the Download folder. So far, so good. I also want to send a GCDWebServerDataResponse responseWithHTML: to show additional information to the user.

Given one GET request, is there a way to send two responses, one with data and one with HTML?

This is not possible due to the way HTTP is designed to work: 1 request = 1 response. If you want an HTML page and also a file to be downloaded, return a first response for the HTML page, then from this page itself, using JavaScript or a redirect, now do the download.
