Different Content Type returned by Tomcat 4.1 and Tomcat 4.0. Pl ease Help!

[Sergei Ostavnenko <so...@Solucient.com>]

Hi,
I've noticed an interesting discrepancy between Tomcat 4.1.x and earlier
Tomcat 4.0.x:  the Response returned by servlets running on Tomcat 4.1.x has
different default Content Type in the Header, then the one that returned by
Tomcat 4.0.x.

Example: 
A servlet is generating an HTML content (by including a JSP) without
specifying explicitly the Content Type. In this case v4.1.x (v4.1.18 and
v4.1.24) would return the content type "text/plain", and v4.0.x (v4.0.1 and
v4.0.2) didn't do it.

The consequences are that the same application is becoming non-compatible
with Netscape Navigator - it treats the output as a text and displays the
Source instead of the Page.  IE is more forgiving, and would work fine as
soon as it sees the HTML tag in the beginning.
And again exactly the same application was working fine with both browsers,
Netscape and IE, when was running from older v4.0.x.

Is it something that was officially changed/corrected when moving from
HTTP/1.1 connector to Coyote? 
Is it a bug that was fixed, or is it a bug that is now?  Is it configurable
in v4.1.x?

I would really appreciate any info on this, since I need to figure out the
best way how can I address this problem.
Of course, for future releases we can deal with it by specifying the Content
Type explicitly.  However, we have a bunch of previous versions of the
application in use, and I need to do something about them, since we moved to
Tomcat 4.1.x, and the problem appeared.  
Adjusting the configuration of Tomcat 4.1.x would be preferable solution,
however I couldn't find any info on this particular setting.

Any suggestions?
Thank you in advance,
