Ticket #818 (defect)

When hosting CherryPy on my Windows Vista Ultimate machine with: CherryPy 2.3.0, Python 2.5.2, Turbogears 1.0.4.4 and Internet Explorer 7.0 or Firefox 2.0.0.1.4

I get the following error after a user has visited a page, and refreshs the page:

 - - "GET /static/images/cars/micro/Mseries.jpg HTTP/1.1" 500 1363 "http://localhost:8080/car/search/3" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC 1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506; InfoPath.2; .NET CLR 1.1.4322)"

Content-Type is being sent back as NoneType?, causing CP to return a 500 error on most static content such as images, css, and js files.

I don't remember this happening when I hosted CP on my CentOS 5.1 box, but maybe it was happening there too.

IRC Log:

<VooDooNOFX> I've got turbogears running on a windows vista box, and whenever I refresh a page, IE seems to not send the content-type to cherrypy, which causes the error above
<@fumanchu> that's the Content-Type of the *response*
<@fumanchu> looks like a bug; please file a ticket
<VooDooNOFX> okie dokie
<@fumanchu> to workaround, either turn off the logdebuginfofilter, patch it to assert Content-Type before split(), or find some way to fill in response.headers['Content-Type'] before CP gets to the logdebuginfofilter
