The client app has a bug that prevents chunked responses from being
unzipped correctly.
Okay, so it's broken. It would be better to put resources into fixing it.
This may not be practical for political reasons, of course.
What control do you have over the client app? ?Can you force it to use
HTTP/1.0? ?What other aspect of HTTP/1.1 do you need?
We use some aspects of HTTP/1.1 so we cannot downgrade the client
application to HTTP/1.0
The only 2 differences between running the web server locally and
running it on the linux server are:
- locally = Win XP ; server = Linux (same version of JRun)
- Linux server has an Apache installed as well
My guess is that the Apache is responsible for doing the chunking, but
I cannot find why and how to prevent it
So hang on, are you using JRun behind Apache, via ajp12 or whatever, or
using its own web server, like Tomcat or something?
If the former, then yes, you need to look into the Apache docs to find out
how to switch off chunking.
If the latter, the only thing that springs to mind is that the default
socket send buffer sizes might be different. If they are, it's possible
that the HTTP server's own servlet output buffers are different sizes
(being sized to fit the TCP buffers). My understanding is that web servers
switch from solid to chunked encoding when (a) they haven't been given a
content-length upfront and (b) they've been given more than a buffer-full
of data. So, different socket buffer sizes might (*might* - this is
speculation!) lead to the onset of chunking at a different output size.
How big is your output, and do you consistently see chunking on linux, or
is it intermittent?
