About persistent http connections

Hi All

We are required to implement a system in C/S structure. The Client have
to send a request to the Server every min. And we use axis2c to send and
recv messages between client and server, and a persistent http connection is
required. my question is how can i establish a persistent connetion from
client to server with axis2c.

Hi,

Did you mean HTTP Keep alive by a persistent connection?

Supun.

Hi
The problem is, we use the API "axis2_svc_client_send_receive" to
send request and receive response between client and server, we hope all the
messages be transfered in only one http connection, but we found when the
client received the response message, it released the connection, and
establish a new http connection for the next request.

Can we send and recv all the messages in one connection? And how to
configure axis2c?

Thanks!

if you use Axis2/C client with libcurl enabled and server with apache2
server(mod_axis2) , You should be able to use send and recv all
messages in one connection (keep alive).

Hi Dinesh

Thanks!
Can you give some example about that? And how to configure Apache2?(I
have already built mod_axis2c)
Thanks a lot!

Hi Dinesh

I have already rebuild my client axis2/c libs with libcurl enabled and
run apache2 with the configurations "KeepAlive On" "KeepAliveTimeout 100"
and "MaxKeepAliveRequests 500" in httpd.conf.
Then I use the api "axis2_svc_client_send_receive" to communicate with
server, and I still found i cannot send and recv all the messages in one
connection.
Is there any other work I have to do? Please help !

Thanks!

If you are using *same* svc_client (libcurl enabled) for sending it should
use a single connection with mod_axis2.

Hi Dinesh,

I built the client with libcurl enabled, and set the right AXIS2C_HOME,
but some error occured while init the svc_client.
If i build the client without libcurl , it works ok.
the log is:
[Mon Nov 10 17:56:35 2008] [error] ..\..\util\src\class_loader.c(167)
Loading shared library
D:\axis2c\axis2c-src-1.5.0\build\deploy/lib/axis2_http_sender.dll Failed.
DLERROR IS DLL Load Error 126:

the version of curl is libcurl-7.15.1-msvc-win32-ssl-0.9.8a-zlib-1.2.3
the version of axis is 1.5.0

please help! Thanks!

I tried with libcurl , one or two weeks back it worked fine. Could you
please check whether libcurl libraries available in the PATH as operating
system be able to load them.

It would be great if you could send us your complete log files.

thanks,
Dinesh
