To add a MIME type to be usable by a domain, login to Plesk and select the domain you wish to add this to.
Once you click on the domain, click on ‘Virtual Directories‘ and then click on the ‘MIME Types‘ tab and click on ‘Add MIME Type‘.
Type in the Extension for the MIME type you wish to add and then click the drop down next to content and select the correct application, if present.
If the application you need is not present in content, you may add it manually in the line below this.
Once done, click ‘OK‘.
If you need any assistance with this process, or encounter any issues, please do not hesitate to contact our Technical Support Department.
