Link context options

The following table describes the purpose of the link context options as well as an example of each. Bear in mind that the accuracy of the XRule results depends on the circumstances. The link context is really just an indicator of the kind of file that the scan expected to find when it requested the link. Because of typographical errors or links that return a 404 custom error page, the expected file might not actually exist. For example, with the link context "Any link to an image file", the XRule limits its search to the Src attribute of the IMG tag. Because of the context, the scan expected that the Src will return a valid graphic file. However, someone might have incorrectly typed in logo.html, when the file was really logo.gif. In this case, the condition will have been satisfied because the scan expected an image file because of the link context. However, the reports based on this XRule would contain a false result. Although logo.html is not an image, it would still display in the reports because the XRule expected an image given its context within a SRC attribute.
