Hi,
I've got a problem with Tomcat processing cookies which contain a umlaut.
Tomcat will throw a 500 internal server error if a cookie containing a
umlaut is set. This can be easily tested by writing "document.cookie='ä=0';"
in the developer console of the browser. The tomcat log will show the
following error:
SEVERE [http-nio-8084-exec-13]
org.apache.coyote.http11.AbstractHttp11Processor.process Error processing

java.lang.IllegalArgumentException: Control character in cookie value or
attribute.

I'm writing some kind of proxy and don't have any influence on the cookies
set by third party webpages. Is there any way of stopping tomcat from
throwing this error?
Greetings Peter
