Hi All - thanks for the advice last week when I asked about using a DOI to retrieve the ISSN from Crossref. I decided to use the content negotiation method that Owen Stephens (thanks Owen!) suggested. I wanted to use Javascript to do this, and I've created two test forms - one that uses jquery and one that uses a XMLHttpRequest request. Both forms work fine in the latest Firefox and Internet Explorer browsers, however I just cannot seem to get it to work with Chrome. Looking at the error I'm getting in the Chrome Development Tool, I'm seeing a "406 Not Acceptable" error.

Jquery Test Form

XMLHttpRequest Test Form
http://voyager.herts.ac.uk/test/doiHttpRequest.html

It looks like the server is just refusing to send the data back. I'm not sure why it does this with Chrome and now the other tow browsers I have tried? As anybody else had experience with this and know of a solution? Is it a bug, or I am just doing it wrong? I can fall back to using a wrapper script on our server which calls curl to get the data, and use this with the javascript. But just interested in why this is not working.

Thanks, Stephen
