ATL Server ISAPI Extension DLL Required to Stream Files (Download)

ATL Server ISAPI Extension DLL Required to Stream Files (Download) **Goal:** Users need to download files off my web server (IIS 6.0 / Win2K3), but I don't want to give direct IIS file level access. I want to be able to control whether they are allowed to download the file or not. **Methods Tried:** All ASP.NET [login to view URL]() - fails miserably. Limited by ASP.NET thread count. [login to view URL]() - client must hit IIS, cannot limit accessibility of file. ASP.NET streaming the file - Standard ASP.NET thread limitations Third party ASP.NET control - Standard ASP.NET thread limitations **Summary of work:** Create an ISAPI Extension DLL, I'm assuming an ATL Server in MSVC6 or Visual Studio .NET / 2003. The ISAPI Extension must accept a filename as a parameter (in the URL?) and from the codebase use that filename as a parameter to open a file and send it to the client. Assume the file can be up to 1GB large. <http://localhost/[login to view URL]> Should basically stream readme.txt. Perferrably with the following headers: [login to view URL] = "application/octet-stream"; [login to view URL]("Content-Disposition", "attachment;filename=\"" + strFileName + "\""); [login to view URL]("Content-Length", ); FYI: I'm looking for an ISAPI Extension, not an ISAPI Filter. **Time Required:** I'm hoping you can find sample code that does this or you already know how to do it. You have 2 days to get the code back to me along with a compiled release DLL that I can test. **Shortcuts:** I am completely willing to accept bids that point me to a ready made ISAPI Extension DLL that is high performance and capable of handling thousands of simulatenously downloads. If you know of one that will suit my purpose, feel free to under bid and provide me with the details after I accept your bid. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
