FWASYNC.dll - File Transfer using Asynchronous WriteClient() inside ISAPI DLL 
 
Overview 
-------- 
FWASYNC.DLL is a sample ISAPI Extension DLL to demonstrate Asynchronous  
WriteClient functionality in the ISAPI interface. This dll illustrates 
how one can use the WriteClient() callback in the ECB to perform an 
Asynchronous IO operation. 
 
FWASYNC.dll sends the file specified on the query string. It also converts 
a virtual file-path (given in the URL name-space) into a physical file 
name using the ServerSupportFunction( HSE_REQ_MAP_URL_TO_PATH) function. 
The ISAPI DLL setsup the callback context and function using the  
ServerSupportFunction( HSE_REQ_IO_COMPLETION) in the ECB. 
 
Installation: 
------------- 
Build FWASYNC.dll and copy the .dll into the virtual directory maked with 
"execute" permissions. 
 
To run:  
------- 
 
Reference FWASYNC.DLL file as a URL from the browser,  
specifying a file-name on the query string. 
 
For example, the following URL entered on the address line of your browser 
will transfer file SAMPLE.GIF, located in WWW root directory: 
 
http://localhost/scripts/fwasync.dll?/sample.gif
