- GenerateHTTPResponse can be used both locally on a desktop system and in the cloud. Certain operations that require extended cloud infrastructure are not supported by GenerateHTTPResponse on local desktop systems.
- The expression expr can contain any of the heads used in CloudDeploy , such as Delayed , FormFunction , etc.
- In GenerateHTTPResponse [expr,req], the request req can be an association of the form returned by HTTPRequestData [] or an explicit URL in the form "url" or URL ["url"].
