I need to access a wiki on a server which uses an authorisation. ( A authorisation before the wiki's authorisation)
How do i do that? At the moment  i am stuck at a "HTTP Error 401"

(In c# i would usuall make use of a webclient and NetworkCredentials)

You can manually add NetworkCredentials to WebRequest in PostDataAndGetResultHTM(), GetPaths() and in UploadImage() function if  required.

Cool! Thanks!
