Problem closing connection in HTTPServletResponse

[Naresh Agarwal]

Hi

I'm developing a webapp using servlets, which processes a HTTP Post
request and sent back MIME message (multipart/related - essentially
SOAP message with Attachments).

I'm constructing the MIME message manually (as I need to stream it to
the client) and writing it to OutputStream (few bytes everytime).

In the end, I close the OutputStream, but still client keeps on
waiting on the socket and it never get -1, while it reads from the
InputStream.

Thus server is not closing the socket even after closing the
OutputStream.

This problem occurs only when I set the content type header in servlet
response as multipart/related. The problem does not occur if I've to
send text/xml or multipart/mixed data.

Does anybody has any clue on it?

thanks & regards,
Naresh

I've seen this problem with certain application server and browser
combinations. For example, JRun 3.0's own admin screen had this problem
when accessed via Netscape.

Experiment with different app servers, browsers and even JVMs.
