Download a file with DefaultHTTPClient and preemptive authentication
- by Nils
After I had a lot of problems with preemptive authentication , I got it finally working.
Now the next problem. I want to get a file with it, but I don't know how.
I thought the file data might be in the variable response, but it isn't.
Any ideas how this might work? I'm trying it since days without success :( - Basically I'm trying to download an jpeg file, which is on a server protected by prem. auth.
