2391	bad parsing of Content-Type (sub_filter_types)	ticket.mmisolution.be@…		"Hello,

I think wefound a bug in the way the Content-Type is parsed in order to match sub_filter_types.

The problem was an href line wasn't rewritten.
After analysibng a lot of the html flux,
We find that the Content -Type line is as follow :

  Content-Type: text/html; charset:UTF-8; charset=UTF-8

It seems that nginx parses such lines as (.*); *charset=(.*)
because we had to put ""text/html; charset:UTF-8"" as the type in sub_filter_types to make it work (eg:

    sub_filter_types ""text/html; charset:UTF-8"" script/js  text/html text/css text/xml ;

It's not an urgent issue, as we found a solution (an ugly one);
but maybe you woulld be interested to know about the issue, and improve it.

Thanks
