[opencms-dev] Can not override mimetype from jsp

[Yves Glodt]

Ok, I got it working, without the cms.setContentType().

The 2 steps necessary to make it work:

* Do not give the file any file extension
* Set the cache property to "bypass"

Without the latter it did not work whatever I did. Here an explanation:

thanks to all and have a nice weekend
