Dear all I have an annoying problem, and would be grateful for any help. I have been trying to MathML-enable my blog, and I have the usual result: it works fine in Firefox but I can't get IE7 to behave. The blog is at http://mat140.bham.ac.uk:8180/blojsom/blog/default/ This address serves the main file as text/html and has incorrect headers, etc. The version served as application/xhtml+xml with proper !DOCTYPE and so on is http://mat140.bham.ac.uk:8180/blojsom/blog/default/?flavor=xhtmlplusmathml As mentioned, it works as expected in firefox. It doesn't work with IE7+MathPlayer however. The text/html version looks as before (maths incorrectly rendered) but the application/xhtml+xml version is just rendered as an XML listing, exactly as you would expect in IE7 when it downloads an XHTML document and no helper or plugin is triggered. This is strange, as there should be enough stuff there to trigger Mathplayer into action. It's just the same as a hundred other pages I have written. Hence the subtitle of this mail: is there somewhere definitive information on what in an xhtml document triggers the mathplayer plugin to do something? (As an aside, I would also quite like to use mathplayer's behaviour - even if there is no visible mathematics in the webpage - to avoid these lengthy XML listings of XHTML.) It gets stranger. To investigate the problem further I wget'ed all the files and put them up on my apache server (the blog itself is served directly from Tomcat5.5). The results are all in http://mat140.bham.ac.uk/~richard/blmath/ In this directory, the document index-default-orig.html is the original default text/html document and index-xhtml-mathml-orig.xhtml is the original application/xhtml+xml document, exactly as I got from wget. I also put in there index-default.html and index-xhtml-mathml.xhtml are the same except I edited these files by hand to make sure that the associated files (css, jpg, js) are all served from the same directory rather than from tomcat. All the names are different, so I don't think there is a content-negotiation issue. As you'd hope, everything looks identical under firefox. But this time with IE7, Mathplayer is triggered and both index-xhtml-mathml-orig.xhtml and index-xhtml-mathml.xhtml display mathematics. So how does IE7/Mathplayer manage to display identical documents served from different servers in such different ways? There are also some problems with the stylesheets and the pages with mathematics aren't actually rendered correctly in IE7/Mathplayer, though they are at least legible. This is something else I need to fix too, in time. Unfortunately, this example is not the simplest (since it comes from the blog software I am using) and there are a number of CSS and JS things in it I need to understand, but I ***am*** worried that MathPlayer and the CSS/JS or whatever it is aren't living together nicely. For the record, I append some of the details of the servers and the HTTP headers they send when I do a wget. (Sorry, the wget agent isn't quite the same as IE7 - but I don't think it really matters. If you want I can do other experiments.) Thanks for reading this far, and (in advance) for any help you might have.
