问题
I'm getting strange hits to a non-existant file on my site called 'pagerror.gif'. From some basic Googling it appears to be a file that Internet Explorer looks for in certain situations.
Can anyone verify that, and perhaps provide some additional information about when IE would look for that file?
回答1:
If I'm not mistaken, pagerror.gif is the image IE shows on error pages. Should be located in res://shdoclc.dll/pagerror.gif. (You can enter that in IE to see the icon)
