You can use the Rebex SFTP in ASP.NET. However, it is not as easy as in ordinary applications.

There are several things to keep in mind:

  • Using the stateful protocol such as FTP or SFTP through a stateless protocol such as HTTP can be quite complicated. In order to be able to devise the best approach to a particular scenario, a certain amount of familiarity with HTTP and FTP/SFTP is needed.
  • ASP.NET environment is multithreaded - several instances of the same page can be processed at the same time.
  • Lot of file transfer operations might take a long time to complete, especially file transfers.
  • Even Connect and Login methods may take a long time to complete, so you probably wouldn't want to call this again and again - instances of the Ftp can be made persistent using an appropriate method.
  • You have to make sure that SocketPermission is granted to your application. This may cause problems with some webhosters who runs client applications under unmodified MediumTrust security level.
