How to cache without parameters?

By default, all the CDNs will cache the resources on your domain with and without parameters (query string). However, VNIS has an option for the system to ignore the query string to make caching more consistent. 

To do this, navigate to ‘Multi CDN’ > ‘CDN Management’. 

Then, choose your target domain. To do this, go to the Operation level panel on the top left side of the platform. On the ‘Site’ panel, select the site where your target domain belongs, and on the ‘Domain’ panel, select your target domain.

Then, click the ‘CDN Settings’ (gear) button on the top right. 

Press 'On' under the 'Ignore query string' section, and finally hit ‘Save’.
