Css background-image hanging IE8 Sophos Web content scanner

fishawack

Hi,

We are developing a web applciation in ASP.Net which uses master pages, themes and stylesheets. Several of the page elements include a background image set through the stylesheet (within a theme).

When running in IE8 on our local machines, we notice that some of these background images are stuck trying to download. This seems to happen regularly but randomly in that it could be when a button is pressed on the screen, when a new page is navigated to or the Browser Back button is pressed.

The images in question are jpgs between 31kb and 1kb each with an example from the stylesheet below:

#templatemo_banner

{ width: 890px; height: 110px; padding: 50px 50px; background: url("images/templatemo_banner_bg.jpg") no-repeat center top; }

The website works perfectly in Firefox and Chrome and also in IE when we disable the Sophos web content scanner so our question is what could be causing this to happen in IE and what could we do on our side to prevent this happening?

Thanks

    Hello,

    We are having the exact same issue as you.  We have ran our pages in the same browsers as you, and only IE has this issue for us as well.  We did as you did and disabled the Sophos "On Access Scanning", and the image(s) loaded fine.

    I look forward to a possible solution as well.

    HI,

    This should be resolved I would think when SAV 10 is released towards the end of the year.  The BHO is being replaced with a LSP for this part of the solution.

    In the meantime you could try some suggestions on this post:

    Has anyone gotten any reponse from Sophos on this?  I am having this same problem with just a regular classic asp site.  After a very long time troublshooting I came across this thread and sure enough this was our problem.  I disabled the Sophos Web Content Scanner in IE and everything started working just fine.

    The problem was this:     We just built a new website and like every website we use CSS.  In this new website the top header wasn't just a regular image with the standard "<IMG" tag in HTML for those of you who are familiar with it.  Instead, we just made the background of a <TABLE> to be that particular image and we did that via CSS.  So the html looked like this:

    <table class=headerBG>

    and in the css stylesheet file:

    TABLE.headerBG {

       background-image:url: ('/Images/headerbg.png');

       background-repeat: no-repeat;

    }

    Pretty basic stuff for anyone knows basic html / css.  The problem was whenever we would load the webpage in IE7 and/or IE8 and click a couple of links and then hit the 'Back' button, that one header image was repeating indefinitely as our background.  We could hit refresh and the webpage is fine, but not if a user just clicked 'Back'  (like a LOT of people do all the time).

    But what I want to know is what the heck is Sophos doing about this?  This first appeared in April of this year and still no resolve????

    Hi,

    We ran an IEFIX.SDB file acquired from Sophos to no avail. The latter is a package created out of Microsoft Compatibility Tool Kit. This affectively tries to apply corresponding settings of IE onto your system. Hence the Sophos engineers couldn’’’’t simulate the problem on their systems. We had to get users to use Firefox as an alternate for sites where Sophos created problems in IE.

    However the problem doesn’’’’t materialise in IE9. Not exactly a fix though, especially for web development purposes where you’’’’ll want cross-platform and cross-browser compatibility.
