Problem with "Transfer-Encoding: chunked" in Apache 2.2

apache-2.2 http axis chunked

18,102

from what i found on apache's web site, chunking is only supported by HTTP/1.1, perhaps your server or software is set for HTTP/1.0 in the configuration. http://ws.apache.org/axis2/1_0/http-transport.html

other than that, i would look at the file indicated in the error message and see if there is any hinting at chunking going on there. {DocumentRoot}/app/webservices/soap.hdb

One of client of our web service uses axis2 application that sends HTTP 1.1 query with:
```
Transfer-Encoding: chunked
```
header. Such a query is refused by our Apache 2.2 with message:
```
<title>411 Length Required</title>
</head><body>
<h1>Length Required</h1>
<p>A request of the requested method POST requires a valid Content-length.<br />
```
In Apache logs there is:
```
[Mon May 17 09:06:04 2010] [error] [client 127.0.0.1] chunked Transfer-Encoding forbidden: /app/webservices/soap.hdb
```
When I send such message without Transfer-Encoding: chunked and with Content-Length all works ok. I searched how to solve this problem, but I found only how to disable Transfer-Encoding: chunked on client side.

As a client I used soapUI where I added/removed Transfer-Encoding: chunked header (when I added this header soapUI do not send Content-Length header). As a server I use: Apache/2.2.3 on CentOS, but I tested it also with "fresh" install of Apache 2.2.15 on Windows.

Is there any way to enable chunked queries on the server side?

Thanks, but the link shows how to configure axis (i.e. client side). I think there is no problem with resource because it can be retrieved with "unchunked" query. Apache HTTP server refuses query without Content-Length and do not try to do anything else with such query.

is there anything in that file that hints at chunking?

Normally {DocumentRoot}/app/webservices/soap.hdb is served by module. But it seems that Apache do not try to execute this module. I can enable debug mode for this module and then it creates log when invoked. For queries without Content-Length such log is not created.

It seems that the module that is used do not accept chunked queries. Thanks!
