[Zope] uploading large files w/ LocalFS

Hi, I am trying to allow remote developers to upload large development tarballs onto our web server using LocalFS. The problem is when upload files are larger than 20MB the server times out. Does anyone have a better solution of allowing users to upload large files onto a Linux based webserver? Is https the right protocol for large file transfer? Any suggestions is greatly appreciated.
