add attribute 'addtimestamp' to tag headinclude to avoid browser caching

[gWestenberger]

This does not work if the headinclude link from the formatter configuration already has a query string (request parameters).

Do you mean the params which are possible in the headinclude tag?

[gWestenberger]

No, the parameters in the link itself. I.e. if you write "/system/modules/.../test.js?param=foo" in the JS link field in a formatter configuration file.

(which would be useful when test.js is a JSP that generates Javascript).
