Things to watch out for... | |||
* '''KeepAlive's''' - Its generally safer to disable keep alives, this causes the FTP session to be dropped after each request. This is less efficient, but leads to more reliable results. If requests don't get completed properly the .NET API gets into a stuck state whereby new FTP requests appear to time-out (though no request actually goes to the FTP server. | |||
* '''Inconsistent Results''' - Results from IIS and non-IIS FTP servers can look different, for example a directory listing on an IIS FTP server results in a basic/raw text result, where as from a non-IIS FTP server this results in HTML rendered text | |||
