• Support for UTF-8 characters, allows to transfer files with filenames containing non-roman characters.
• Support for FTPS (Implicit mode only)
• Logging with log rotation
• Support for HTML form upload with progress bar – with a redirect after transfer
• Support to transfer files larger than 4GB
• administrative console to monitor usage
• FXP (or server to server transfers) capabilities when used in conjunction with UnlimitedFTP Pro Applet
• Support for G6 FTP server

What is an FTP Tunneling Servlet?

If you are unfamiliar with the UnlimitedFTP Servlet, the short version is that it acts as a proxy between HTTP traffic and your FTP or FileCatalyst Server.

The main benefit is virtually failure-free connectivity. Some organizations block FTP wholesale. But for those organizations to allow access to the internet (and very few businesses could operate without internet) they are obviously permitting HTTP. If an organization permits HTTP, their users can transfer to and from the FTP Tunneling Servlet. Then, the servlet acts as a “relay”, letting communication and data transfer reach your FTP or FileCatalyst server.

Another huge benefit is that as the organization with the FTP or FileCatalyst Server, you can shield it from direct access over the internet, using the Tunneling Servlet as the go-between. Not only does this add a layer to security (FTP connections will only occur within your network), but if HTTPS is already enabled on your web server, you can leverage the encryption benefits without configuring your server for FTPS/SFTP (although FTPS support is also available).

If you are using the Unlimi-Tech applets in standalone form (UnlimitedFTP, U-Upload, UDownload) then this article is for you. If you are using the applets as part of one of our web offerings–FileCatalyst Webmail (Formerly Files2U) or FileCatalyst Web Workflow (formerly Doctera) this article is NOT for you.

Once every so often (every two years to be precise), our applet customers–even those with perpetual licenses–must update their applets. This is because we use digital signatures to guarantee the safety of the applet. One interesting analogy compares this process to the “shrink wrap” of a physical product you might find on a store shelf. By digitally signing, Unlimi-Tech is guaranteeing that when you install our applets, they have not been tampered with.

However, digital signatures, like any other security certificate, must be updated. Although applet functionality is maintained (end-users simply select “Trust” or “Run” from the warning dialog), the certificate itself has expired.

We update these in-house and then roll out new versions of the applets. To get the benefits of the security certificate (and make any browser nag dialogues go away) you need to upgrade your applets with the latest version from the website. If, after upgrading, you are still seeing the nag dialog, please contact Unlimi-Tech in order to have the situation resolved. Read More… »
