Security! Does PDF.js Express allow to disable browser cache for PDF form values populated by User?

Which product are you using?

PDF.js Express Version

Detailed description of issue
{My project is related to Healthcare organizations in the US and requires the highest security attention. Users will be populating PDF forms with personal and sensitive data which should be totally secured.
Before start using our service, I need to know the answers to the following questions?

  1. Does the browser cache PDF-form’s values in your PDF viewer realization?
  2. Does your service itself have its own layers of cache that is related to the PDF form’s values?
  3. If there is at least one answer for the first two ones like YES, is it possible to disable caching and guarantee that no user-inputted data will not be stored in the Browser?}

Expected behaviour
{PDF form’s values should not be cached by browser}

Does your issue happen with every document, or just one?

Hi there,

We do not do any form caching on our end - any caching you may be seeing would be a result of browser caching which we do not control.
