I see that we can update our headers:
 * Expires: Fastly recommends to remove but Mozilla is more conservative: keeping
 * Pragma: same
 * Cache-Control: same + adding private
 * Cache-Control post-check and pre-check: according to Stackoverflow and especially Microsoft, removing
 * x-frame-options: see my comment in user ML at [https://markmail.org/message/hcw7du22vqcbe4oo] TL;DR better to use a CSP policy
 * x-ua-compatible: it's only in html files. I think it's more history and cargo cult, but I'll though ask on dev ML
 * others: we are not concerned :)

I have attached the OFBIZ-6766-UtilHttp.java.patch and will ask about x-ua-compatible on dev ML before committing
