PIX 535 V6.3(2) and Java filtering...

vgrigaliunas — Fri, 21 Feb 2020 06:53:50 GMT

Hi...

We've noticed that web pages with embedded Java applets take an inordinately long time to download when opened from behind the PIX, even though supposedly there is no filtering enabled on the PIX.

Does anybody else see this ??? Could it be that the PIX is still scanning the page even though filtering isn't enabled ???

Thanks...

What you might be seeing is the time taken for initial download of large Java applets (and downloads of the same applets if they are not being cached locally). Delays as long as six minutes have been observed. The problem might also be due to virus scanning. Some virus scanners are configured to automatically scan content downloaded by browsers and those might be slowing down the download.

Hi...

Thanks for your reply...

The problem is when we move from behind the PIX (in front of the PIX in other words), the applets download very quickly...we make sure to clear the cache each time we test...

Thanks...
