[EMAIL PROTECTED] How to make Apache 2.x as Forwarding server?

[Anand Kulkarni]

Hi,
 
I have client/server architecture. I want to introduce Apache server in
between that will receive request from client, forward it to server then
take response from server and give it back to the client. There is no
load balancing or complex processing here.
 
How can I implement this simple requirement without using mod_proxy?

It is a pure java application. We have developed TCP Server & TCP client
using Java's standard java.net.SocketServer & java.net.Socket classes.

Because we have many TCP servers running and using mod_proxy we want to
route client request to the specific one.

Also using Apache as proxy, we can get benefit of different services.


>> Hence, we are trying Apache mod_proxy module.

>simple tcp redirector or evan NAT probably. Highly depends on answer to
my previous question

What is NAT. We want only open source proxy servers. If you know
anything please let us know.

We have already developed an application where TCP-client communicates
with TCP-Server. Its working fine.

But now we want to introduce some proxy server in between. Hence, we are
trying Apache mod_proxy module.

Is it wrong to use mod_proxy in this scenario? If YES, then Is there any
other possbile way of introducing proxy in between?

[EMAIL PROTECTED] Any replacement of mod_proxy?

[Anand Kulkarni]

Hi,
 
We have used mod_proxy in our project for configuring proxy server
between TCP client and TCP server. But, mod_proxy has not been able to
forward the complete client data to the server.
 
I think it is a bug with mod_proxy. We have another option called
mod_athena. In that also it did not work.
 
Is there any replacement of mod_proxy in Apache?

RE: [EMAIL PROTECTED] How to configure Apache 2.x for HTTP 1.0 version?

[Anand Kulkarni]

Hi,

I want HTTP 1.0 protocol because I heard that passing content length in
HTTP 1.0 request is not mandatory.

In my application, the client does not know the length of data to be
sent to server through Apache as proxy. When I switched to HTTP 1.0
still its forcing content length in the request.

Do you know how to send dynamic data from client without specifying
content length?

What do you mean by 'persistent'?

Keepalives off

work for you?  That gets you rid of the Keepalive feature without 
doing away with the rest of the protocol features.

[EMAIL PROTECTED] How to override Apache default headers?

[Anand Kulkarni]

Hi,
 
I am using mod_proxy to establish proxy communication between TCP client
and TCP server.
 
When I send request from client to server through Apache as proxy,
Apache adds the following headers automatically:
 
POST / HTTP/1.1
Host: 192.168.56.17:9801
X-Forwarded-For: 192.168.56.17
X-Forwarded-Server:   www.abc.com
Connection: Keep-Alive
Content-Length: [Specified from client side]
 
How can I ask Apache not to send such headers to the TCP server?

[EMAIL PROTECTED] How to customize Apache Headers?

[Anand Kulkarni]

Hi,
 
I am sending many requests from TCP client to Apache. Using mod_proxy it
will be routed to the destinition server.
 
In every client request, I want to send different HTTP headers but I
found that Apache adds its own headers and does not allow client to set
request specific headers.
 
So, my question is How to customize Apache Headers from the client side?

[EMAIL PROTECTED] MOD_PROXY a strange problem!!!

[Anand Kulkarni]

Hi,
 
I have a TCP client-server application written in Java using the
standard socket APIs.
 
Now, I want to introduce Apache as the proxy server between them. And
hence I am using the mod_proxy module.
 
The communication among client, apache and server is properly being
established but facing a strange problem. 
 
Here the client wants to send many requests, so I am writing the code
as:
 
CLIENT:
 
/** 1st Request [START] **/
contentLength = 6.
out.writeBytes("A");
out.writeBytes("B");
out.writeBytes("C");
out.flush();
/** 1st Request [END] **/
 
/** 2nd Request [START] **/
contentLength = 6.
out.writeBytes("P");
out.writeBytes("Q");
out.writeBytes("R");
out.flush();
/** 2nd Request [END] **/
 
/** 3rd Request [START] **/
contentLength = 6.
out.writeBytes("X");
out.writeBytes("Y");
out.writeBytes("Z");
out.flush();
/** 3rd Request [END] **/
 
out.close();
 
 
The request properly goes to Apache without any exception on client
side. 
But the server receives very data only for 2 requests:
 
SERVER:
 
POST / HTTP/1.1
Host: 192.168.56.17:9801
X-Forwarded-For: 192.168.56.17
X-Forwarded-Server:   www.pavan.com
Connection: Keep-Alive
Content-Length: 6
 
ABC
PQR
 
This is because of content length is 6. If I increase it to 9 then it
works perfectly.
 
See here every request is sending its content length. But apache
considers all 3 requests as the part of single request.
 
How to convince Apache that the client wants to make 3 separate
requests?
 
Waitng for the reply.
regards,
 
Anand

Hi,

I have tried for Apache 2.2 as well but it did not work.

You may give me solution for any Apache version.

RE: [EMAIL PROTECTED] Unabling Chunked encoding in Apache

[Anand Kulkarni]

Hi,

I got a desktop client application that sends HTTP request to Apache
using HTTP tunneling. See the sample code at:
http://java.sun.com/j2se/1.5.0/docs/guide/security/jsse/samples/sockets/
client/SSLSocketClientWithTunneling.java

The data is sent using POST method (I tried for GET as well).

I am sending a plain text data so the content type is text/plain.

Sorry...
I did not read the OP's question well enough, and failed to click that 
he was talking about sending large chunks of data from client TO Apache 
server.  My mistake, I apologise.

To the original poster :

Could you explain a little bit about the client who is sending the data
?
- what kind of client is that ?
- how is it sending it ? via a POST ?

I mean, are you talking about a browser with an html form with a  or about something else ?

Thanks

RE: [EMAIL PROTECTED] Unabling Chunked encoding in Apache

[Anand Kulkarni]

Hi,

I have also seen about chunk data at
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html

Refer to the section "Request Bodies" & "Reverse Proxy Request Headers".


For Apache 2.0.63, inside httpd.conf file I set the environment:

SetEnv proxy-sendchunked 1

But it did not work. Have somebody implemented this concept?

I could swear that I saw something about that in the mod_proxy

Hi,
 
I want to send large amount of data from client to server through

module.
 
Client does not know the length of data to be sent and hence can not set

[EMAIL PROTECTED] MOD_PROXY not working!!!

[Anand Kulkarni]

Hi,
 
I am working on mod_proxy module for Apache 2.2.8. My client is sending
5 HTTP messages to Apache. 
 
It is expected that the Apache will forward those messages to actual
server. But, Apache just forwards the first message. Here is the message
printed on server console:
 
POST / HTTP/1.1

Host: 192.168.56.17:9802

X-Forwarded-For: 192.168.56.17

X-Forwarded-Server: www.pavan.com

Connection: Keep-Alive

Content-Length: 329

-fvn0gnrookl

DataRecord===com.fxall.ems.infra.EMSDataRecord{USER_ID=Anand,EVENT_ID
=1000}===

Content-Type: text/plain 

-fvn0gnrookl--

POST / HTTP/1.0 Content-type: text/plain;
boundary=---xagueiifv29

Content-length: 329

-

 

Can you please tell me how I can receive all 5 messages to server
console?

regards,

Anand
