WS_FTP Server Web Transfer Client Configuration

WS_FTP Server Web Transfer Client does not require installation on a user's computer. Your WS_FTP Server users can access the files in their accounts using the web browser of their choice, and the address (URL) that you provide them.

However, you must administer the following changes in WS_FTP Server Manager:

  1. From your existing set of WS_FTP Server users, add users to the Web Access list.
    1. Log in to the WS_FTP Server Manager, and select Home > Modules. The Modules page opens.
    2. Select Web Transfer Access.

      The Web Access page shows all eligible users, which is all users on all of your WS_FTP Server hosts.

    3. Add any users to whom you want to provide web access.
  2. Roll out Web Transfer Access to your users by providing them the address (URL) that users will use to log on to the Web Transfer Client.

    The address is: http://<local_machine>/thinclient/

    where <local_machine> is the domain name of the computer on which you installed the Web Transfer Client. If you specified a port other than port 80 during installation, you need to enter it in the address.

    For example, if the local computer domain name is, then the address your users need to log on to the Web Transfer Client is:

    You should test this address from a remote machine before sending it out to users.

    You can also launch the Web Transfer Client from the WS_FTP Server program group (Programs > Ipswitch WS_FTP Server > WS_FTP Server Web Transfer Client.)

    If you add a user to the default host (specified in Server > Server Settings > System Details), the user will log onto the Web Transfer Client using their WS_FTP server user name and password. If you add a user to a host that is not the default host, the user must log onto the Web Transfer Client using the host name, host separator, and username and password; for example:

Secure Transfer via HTTPS

For secure transfer, the Web Transfer Client is installed with SSL capability, which runs on port 443. The installation creates an SSL certificate which is used when the user connects via HTTPS. You can enable secure transfer by changing the address used to log on to the Web Transfer Client to use HTTPS, for example:

If you specified a custom port (other than the default port 443) during installation, you need to enter it in the address.

Increase IIS 7.0 MaxAllowedContentLength

If your server is running IIS 7.0, users may not be able to upload file larger than 30 megabytes, receiving the following error:


To correct this problem:

  1. Open the following file with notepad: %windir%\system32\inetsrv\config\applicationhost.config .
  2. In this file, locate the <requestFiltering> node.
  3. Add a value that matches the size of the Content-Length header that the client sends as part of the request. By default, the value of the maxAllowedContentLength property is 30000000 (The value is in bytes, so the above value is about 30 MB.). Increase this number so that it will match the largest file size that you expect users to upload.

    For example, modify the following:

    <requestLimits maxAllowedContentLength ="30000000" />

    to increase the value to 1073741824, which equals 1 GB:

    <requestLimits maxAllowedContentLength ="1000000000" />

  4. Save the ApplicationHost.config file.
