- This sample is intended primarily to demonstrate http read range but can also
- be used for simple GET requests without ranges. Application writers may be
- interested in plugging into the interface defined in range.h, one C call to
- initiate the request and one C callback to receive status and data.
-
- Other interesting aspects include...
-
- Urlmon
- * use of urlmon from a console app (not required)
- * correct use of IStream::Read return values
- * implementation of IHttpNegotiate to add request headers
- * use of IWininetHttpInfo to parse response headers
-
- Wininet
- * passing INTERNET_FLAG_OFFLINE to InternetOpen
- * calling InternetSetFilePointer in offline mode
- * calling InternetTimeFromSystemTime
-
- Files included in this sample...
- range.h HttpReadRequest constants, structures, and prototypes.
- range.c test stub (omit when linking app with remaining files)
- cache.cpp HttpReadRequest entry point and wininet cache handling.
- download.cpp HttpReadFromServer entry point and urlmon downloading.
- makefile makefile for use with inetsdk.mak (note console=1)
-
- Limitations
- * Microsoft-IIS 2.0b2 may omit some boundaries between multiple ranges.
- * Netscape-FastTrack 2.0b3 claims to accept ranges but never returns them.
