I'm attempting to do something strange by visiting URLs and expecting a 404 response. It looks like installshield automatically retries 6 times when it hits a url and gets a 404 response. Is there any way to prevent retries like this and just attempt a URL once? It only runs the OpenFile function once as you expect, but somewhere inside there it sends 6 URL requests.
I've tried a number of different methods, such as OpenFile, CopyFile, ExistsDir, GetFileInfo, and they either retry 6 times or 12 times in the case of Copy.
Or, is there another way of hitting a URL within installshield that is different?
I'm not aware of a way to configure this (and I see the same six-requests behavior with Is(FILE_EXISTS, "http://example.org/testing.html")). Perhaps look into prototyping and calling the InternetOpen, InternetOpenUrl, and InternetCloseHandle API functions directly from wininet.dll in your InstallScript code?
