dflet | 0:6ad60d78b315 | 44 | * There are two layers in this module: |
dflet | 0:6ad60d78b315 | 45 | * - The lower layer consists of HttpResponse_Headers() and HttpResponse_Content(). These routines allow the caller to specify all details of the response. |
dflet | 0:6ad60d78b315 | 46 | * - The higher layer consists of HttpResponse_Canned*(). These routines emit canned (pre-made) responses, such as redirects and errors, which are useful in many situations. |
