I've successfully created a small demo HTML report of test results from a build. Simply put, I'm doing numerical computations, and would like to give more detailed information on test results than a binary pass/fail. The HTML report consists of multiple HTML files with relative links between them.
However, linking to one file from the other sometimes leads to the file being opened in the browser, and sometimes a "download file" dialog opens. Any ideas what the rules are, so I can look at the whole report in-browser without resorting to downloading a zip file of the whole report, unzipping, etc etc?
