Re: IIS 6.0 and Connection Keep Alive
Can you give the IIS configuration as well as exact request that triggers
this? In particular, the applicable ScriptMap setting for the specific URL,
any ISAPI Filters installed globally/per-site, as well as the requested URL
+ request headers.
It is possible for middleware running on IIS to make it generate such
responses.
For static files, IIS static file handler knows and sends the content-length
header. So, I suspect that you have something configured on IIS which is
altering this behavior - I suspect your pages are not being handled by the
IIS static file handler but some other ISAPI.

Re: IIS 6.0 and Connection Keep Alive
Hi Wang,
I am told that the responses, though static,are served by a Servlet
engine.
Here is a sample request and its response header.
Would this mean that the ISAPI filter configuration has a problem ?
I am a novice on IIS and i am not sure how it works. Can you give me a
sample Script
map setting that may do this ?
Since i dont have access to the webserver settings i am not able to get
the IIS settings.
I am doubly sure that the middleware (it runs outside the IIS) does not
do anything with this since the same response is sent even when we
access it directly without the middleware.
GET /servlet/nbTest HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/x-shockwave-flash, application/vnd.ms-powerpoint,
application/vnd.ms-excel, application/msword, */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; DigExt)
Host: 192.168.2.69
Connection: Keep-Alive
HTTP/1.1 200 OK
Date: Tue, 28 Feb 2006 01:05:55 GMT
Server: Microsoft-IIS/6.0
Content-Type: text/html
Thanks
