How can I fix the "Missing Dependency file with target name space..." error while uploading WSDL files onto the Barracuda Web Application Firewall?

Solution #00005873

Scope:

This solution applies to the Barracuda Web Application Firewall, model 660 and above, all firmware versions.

Answer:
This error is generated if the soap encoding schema file is not uploaded onto the Web Application Firewall.

To fix this, please visit http://schemas.xmlsoap.org/soap/encoding/, and save the resulting page as "soapschema.xsd".

After saving the file, import this file on the Web Application Firewall (under "Websites > XML Validations > Import Schema/WSDL").

After this file is uploaded, the WSDL file should upload without error.
