How do I download a file from LiveLink using c#?

Question

I am writing a c# agent to pull data out of Excel workbooks stored in Livelink but I am unable to download the files.

webClient = new WebClient();
webClient.Credentials = CredentialCache.DefaultCredentials;
webClient.DownloadFile(strFileLocation, TEMP_FILE_LOC);

This is the code I am using to save the file. strFileLocation is a link generated using the make link utility in Livelink and it is a http link

Here is the code

(http://LivelinkServer.com/Livelink/livelink.exe?func=ll.GetTZ&NextURL=%2FLivelink%2Flivelink%2Eexe%3Ffunc%3Dll%26objId%3D128027626%26objAction%3Ddownload%26viewType%3D1)

I get an excel document that has a progress bar that says "Please wait a moment while Livelink is loading..." this looks, to me, like the page that redirects the request in order to get the actual file.

I appears to use a double hop in order to direct you to the file on the Livelink server via the URL it gives you, but I do not know what webservice it calls, examining the response headers gives no clues.

Does anyone know how to correctly access a file on a Livelink sever?

Any help would be greatly appreciated, thank you.

Thankyou for your answers but after contacting my companies livelink department, I found that I need to access this service on a seprate port to allow the correct type of authentication
