HTTPS site v.slow to load through IE & Chrome

psmithne
Hi,

We've noticed that any https site takes 5-10 seconds to load when using IE and Chrome.  Firefox is fine.  I can reproduce this reliably by searching 'lastpass' in Google and clicking the first result.  Google Results page will sit there for 5-10 seconds and then suddenly jump to the LastPass home page.

If I enable my LastPass plugin for IE, it also takes 5-10 seconds to load my browser.  Disable it and it loads fine.

Internet Explorer 9
Latest Chrome
Firefox 21.0

We're running in Standard AD SSO mode on an ASG220 running 8.309.  HTTPS scanning is disabled.  No application filtering.

Anyone seen this behaviour before?

Thanks,

Paul

    Hi, I'm not sure if this is the issue or not, but many newer browsers do more checking...
    "reputation checks"
    "revocation list checks for SSL certs"
    ...

    I would recommend looking at all the logs, and consider running a sniffer.

    Hi BarryG,

    Yes, this indeed was the issue.  The browser and plug-ins were struggling to reach CRL servers.

    Setting WinHTTP to point at our ASG 220 fixed things: 

    netsh winhttp import proxy source=ie


    Cheers

    Paul
