    HttpException for ImageGen.ashx

    I keep getting errors (over 100 a day) in my error log where the path looking for ImageGen is not correct by it looking in the directory where it is already. Here is the exception:

     

     

    System.Web.HttpException: The file '/accessories/umbraco/ImageGen.ashx' does not exist.

    I can never see this error when I go to the page (tried in many different browsers). It is only in the error log.

    I am never using relative paths. Here is the HTML code produced on the page for the image src:

     

    src="/umbraco/ImageGen.ashx?image=/media/18914/acs%20duocom.jpg&width=120&height=80&Constrain=true"
    

     

    I am actually guessing that it has nothing to do with ImageGen but the ImageGen resource is the only thing that ever shows up with this error. 

    Umbraco version 4.0.4.2

    SQL Server 2005

    ImageGen version 2.0.1.0

    Any ideas?

    Don't think it is related to ImageGen at all. You might check your webserver log for requests to /accessories/umbraco/ImageGen.ashx and see where those requests are coming from. Might be a bad macro or a spammer, for instance.

    Or maybe you're rewriting the url and you're not aware of that? Check Url rewriting for rules which could match the imagegen url.

    I don't think it is spammers or robots because they are coming from different IP addresses, and I can see them coming from different browsers (IE6, IE7, Firefox on Mac, Safari on Mac).

    It is probably not related necessarily to ImageGen but ImageGen is the only resource that is coming up (not non-image gen images or CSS or javascript files).

    I don't think it is a bad macro as when I go to the pages, I can never see the error and I always see the pictures.

    Good thought about the URL Rewriting but I am not using any redirects or rewriting on the site. As in, there are no entries in the '/config/UrlRewriting.config'
