| 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. | |
