CTETEST.DLL is a sample ISAPI HTTP Extension DLL to demonstrate Chunked  
Transfer Encoding. The Chunked Transfer Encoding modifies the body of a  
message in order to transfer it as a series of chunks, each with its own  
size indicator. Unlike "normal" HTTP file transfer, Chunked Transfer  
does not need to specify (or even know) the transfer length in advance.  
There is no "Content-Length:" header transferred. For complete details  
about Chunked Transfer Encoding, see section 3.6 "Transfer Codings" of  
the latest HTTP/1.1 specifications, available from  
http://www.w3.org/Protocols. 
 
 
CTETEST.DLL sends the file specified on the query string. If no query  
string is present, or if the query string does not identify a readable  
file, CTETEST.DLL will return a plain text page describing its usage. 
 
To install:  
 
Build the CTETEST.DSP project and copy the .DLL into virtual directory  
with "execute" permissions. 
 
To run:  
 
Reference CTETEST.DLL file as a URL from the browser (currently only  
Microsoft Internet Explorer version 4.xx supports chunked encoding),  
specifying a URL on the query string. 
 
For example, the following URL entered on the address line of Internet  
Explorer will transfer file SAMPLE.GIF, located in WWW root directory,  
encoded in 1024-byte chunks: 
 
http://localhost/scripts/ctetest.dll?file=/sample.gif+chunksize=1024
