I had the same problem a while back when i wrote an ISAPI DLL to execute
proprietery scripts. I ended up using the SCRIPT_NAME server variable to
find out the name of the script being called and then extract the path.
ie
/example/scriptname.jasp
or if your calling the isapi dll directly
/example/example.dll
then i used the "HSE_REQ_MAP_URL_TO_PATH" server function to map the virtual
url to a physical path
i.e.
function mapURLToPath (const ECB : PECB; const url : string) : string;
var
buffer : array [0..1023] of char;
dwLen : DWORD;
dwDataType : DWORD;
begin
result := '';
if length (url) > sizeOf (buffer) then
exit;
fillChar (buffer, sizeOf (buffer), 0);
strPCopy (@buffer, url);
dwLen := sizeOf (buffer);
dwDataType := 0;
if ECB.ServerSupportFunction (ECB.ConnID, HSE_REQ_MAP_URL_TO_PATH,
@buffer, @dwLen, @dwDataType) then
result := buffer;
end;
It only works when a page is being requested. Seemed slightly messy but it
was the only way i found.

Subject: [DUG]: Some ISAPI Questions...
Hi all,
I just have some questions on building ISAPI dlls.
First... I want to find the dir where my dll is running. The
PathTranslated seems to return wrong information. From the documentation
it looks like PathTranslated is what I want, but it doesn't work as
expected.
On the web server machine I have a Home directory as D:\Inetpub\wwwroot
(not to sure what a home directory exactly means). I also have a virtual
directory /Test which points to D:\InetPub\Test. My ISAPI ISAPITest.dll
is located in D:\InetPub\Test\Scripts.
>From a web browser, I can go
computername/Test/Scripts/ISAPITest.dll/Test and I get a path translated
D:\Inetpub\Test which is correct, all fine and dandy.
Then I go computername/Test/Scripts/ISAPITest.dll/Test2 and I get a path
translated D:\Inetpub\wwwroot\Test2.
So it seems if my URL path matches my directory path all seems to work.
If my URL path does not match (which will usually be the case) I get the
home directory coming in.
To summarise... I am a bit confused! I just want to get the path to my
dll in code so I can use this in the generated html scripts to make it
easier to move the dll from server to server, directory to directory...
I have other questions... But I shall try and solve this one first.
Any help appreciated.
Regards
Colin
