 Gavin LaRose - pagerror, refresh gif files  11/7/2005; 1:55:56 PM (reads: 1096, responses: 6) Hi all, What is "pagerror.gif"? I'm finding a lot of error log messages from our Gateway test testing that complain about not finding a display module for pagerror.gif. But I can't figure out what pagerror.gif is supposed to be, or where it's supposed to be. Similarly for "refresh.gif". Thanks, Gavin <| Post or View Comments |>

 Michael Gage - Re: pagerror, refresh gif files  11/7/2005; 2:25:35 PM (reads: 1139, responses: 0) Hi Gavin,Something --- hard to say what right at the moment --- is returning a url to the browser asking it to fetch the relative path pagerror.gif Since the browser was last pointed to /webwork2/ma215f05/7/3 it assumes it needs /webwork2/ma215f05/7/3/paperror.gif and asks for it. The dispatcher in WeBWorK.pm (and URL.pm) has no clue what is being asked for and gives this error. I'm afraid I can't guess what error sends back a reference to paperror.gif -- probably something with in the bowels of the Apache server perhaps? You might try locate pagerror.gif and see if you find something. Hope this helps. Take care, Mike <| Post or View Comments |>

 Gavin LaRose - Re: pagerror, refresh gif files  11/7/2005; 3:33:06 PM (reads: 1143, responses: 0) Hi Mike, Thanks. With a little further investigation, it appears to be the case that the error is only generated by MSIE 6.0, it is only generated on requests for /webwork2/ addresses (though it occurs for both homework and gateway test addresses), it only occurs for requests for the ProblemSetList page, Problems in homeworks, and Gateway quizzes, and it started when I upgraded WeBWorK from the CVS at the beginning of the semester. I haven't tried upgrading from the CVS to see if some subtle change since the last time I did that has fixed the problem because we're "in production" and I don't want to elicit screams of protest if I break something. Any thoughts or comments are welcome. Further announcements as events merit. Gavin <| Post or View Comments |>

 Sam Hathaway - Re: pagerror, refresh gif files  11/7/2005; 10:17:33 PM (reads: 1149, responses: 0) pagerror.gif is the name of the icon that IE shows on error pages (like when it can't load a page. It's usually located at  res://C:WINDOWSSystem32shdoclc.dll/pagerror.gif. Here's someone who ends up with pagerror.gif appended to image URLs, but he was working with an IIS server: http://archives.neohapsis.com/archives/vuln-dev/2003-q4/0138.htmlNot much else forthcoming. I assume you've checked the HTML that webwork is sending and haven't found any reference to this mystery file. <| Post or View Comments |>

 Gavin LaRose - Re: pagerror, refresh gif files  11/8/2005; 2:50:43 PM (reads: 1185, responses: 0) Hi Sam, I went through with a find -exec grep pagerror.gif... in the WeBWorK directory and couldn't find anything, so I'm inclined to think that it's something to do with IE requesting the file for some reason. Thinking about it today, I'd bet that it's something to do with not finding some image that it needs from the images that jsMath mode uses to do its display. Not finding that, it looks for the "image not found" image, which of course doesn't exist either. If this is the case, it's likely that when I update PG from the CVS there's a chance that the error may go away. Thanks, Gavin <| Post or View Comments |>
