| 31 | /** | ||
| 32 | * The HttpReceiveSocket class extends the WrappedSocket class | ||
| 33 | * by removing the HTTP protocol packaging from the input stream and | ||
| 34 | * formatting the output stream as an HTTP response. | ||
| 35 | * | ||
| 36 | * NOTES: | ||
| 37 | * | ||
| 38 | * The output stream must be explicitly closed for the output to be | ||
| 39 | * sent, since the HttpResponseOutputStream needs to buffer the entire | ||
| 40 | * transmission to be able to fill in the content-length field of | ||
| 41 | * the HTTP header. Closing this socket will do this. | ||
| 42 | * | ||
| 43 | * The constructor blocks until the HTTP protocol header | ||
| 44 | * is received. This could be fixed, but I don't think it should be a | ||
| 45 | * problem because this object would not be created unless the | ||
| 46 | * HttpAwareServerSocket has detected the beginning of the header | ||
| 47 | * anyway, so the rest should be there. | ||
| 48 | * | ||
| 49 | * This socket can only be used to process one POST and reply to it. | ||
| 50 | * Another message would be received on a newly accepted socket anyway. | ||
