Does Socket support proxy servers?

Hello,
I was wondering, if one was to create a Socket and then
connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the
Internet, would this
connection succeed or fail?
Also, I assume that the URLRequest / Loader classes do in
fact get through proxy servers.
Is that correct or not?
Thanks for your insight.

Creating java sockets behind proxy servers.

Hi,
I am trying to create a socket to an external server(i.e. a public server) from behind a proxy firewall, but the socket creation statement throws an IO exception. Can someone please let me know how to create sockets using proxy servers.
TIA
Shishir

I tried using java.net.Proxy for the connection. But the socket to the proxy itself is not getting created. It throws the IllegalArgumentException.
import java.io.*;
import java.net.*;
import java.net.Proxy.Type;
public class Client {
static Socket proxSocket = null;
static PrintWriter out = null;
static BufferedReader in = null;
public static void main(String[] args) throws IOException {
try {
System.out.println("Trying to create socket");
InetSocketAddress proxyadd = new InetSocketAddress(InetAddress.getByName("148.87.19.20"),80);
Proxy ps = new Proxy(Proxy.Type.HTTP,proxyadd);
Socket proxSocket = new Socket(ps);
out = new PrintWriter(proxSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(
proxSocket.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host: ...");
System.exit(1);
} catch (IOException e) {
System.err.println("Couldn't get I/O for "
+ "the connection to: ...");
System.exit(1);
catch(IllegalArgumentException e)
System.err.println("Unable to describe the proxy.");
System.exit(1);

Folio Builder does not support proxy authorisation on the mac.

Folio Builder does not support proxy authorisation on the mac.
Which’s solution to connect ?

It does not work because the Folio Builder tries to connect to the proxy as "anonymous". I don't know any solution up to now... Anyone?

NI Installers & downloaders do not support proxy servers requiring authentication

Hello, I'm posting this on the LabVIEW forum since it applies to the LabVIEW installer and evaluation version downloader, but it also applies to other products that use the NI meta-installer framework and other products that use the NI downloader.
We are behind a corporate firewall which requires the use of a proxy for internet access. In addition, the proxy requires authentication, which I believe is the complicating factor.
When running an NI installer, if we check the box that requests that the installer contact NI for new notifications, this will inevitably fail when trying to connect to the notification server.
Also when trying to use the NI downloader to download drivers or other products, the download always fails.
Most other software (e.g. Browsers, Dropbox, etc.) are able to use the proxy and allow entry of the username and password (either through a pop-up username/password dialog or configuration page).
This has generally not been a showstopper problem, but since it affects the NI installer framework it impacts many products and thus they would all benefit from a single bug fix.
Thanks,
Joe

Hi GeekySeb,
Are you using the most current versions of the NI Downloader and NI Update Service? The problems with proxy servers have been repaired in both of them.
You can download the current version of the NI Update Service here, either by using the NI Downloader or by downloading the installation file directly. This option should exist for most of our software downloads, so if the NI Downloader does not appear to be working for you then there is an alternate download option.
http://www.ni.com/download/ni-update-service-14.0/2617/en/
If none of these options work for you, I would recommend contacting your company's support group for help in configuring your firewall to be able to download NI's software.

Sockets through proxy servers

im facing a problem.in which I am having,one java application that is sitting behind Proxy1 has to access the Webserver which is sitting behind proxy2,for transfering files. from one M/C tht sitting behind Proxy 1 to the webserver sitting behind proxy 2.
using URLConnection i will be able to do this,but as per my requirement i may have to transfer files which may be more than 100 MB,in that case URLConnection is failing because of OutofMemmory Error,
the only way to cater this requirement is socket but i don't know hw i can go through proxy using java sockets......
---------------------------Proxy1------ Proxy2
-------------------------- --|----------------|
Java Application -------| <----->------|----- My WebServer
-----------------------------|-- internet---|
---------------------------- |----------------|
Thnx in advance,

Thnx tolmank,
i am using sockets instead of URLConnection,i was able to connect using URLConnection,but when i use sockets i am not able to,i cann't use URLConnection because of out of memmory problem,as i mentioned earlier .
if anybody can me help me out it would have been a great help for me...
thnx in advance......

IIS proxy 5.1 and Weblogic 6.1 does not support sticky session

Dear Sir,
Our system is migrating from Weblogic 5.1 to Weblogic 6.1. After testing on
development environment, it is found that IIS proxy for 5.1 plug-in and Weblogic
6.1 server is perfect match for our case. Since our appliction system hit some
bugs of IIS proxy for 6.1. In development environment, one IIS match with one
Weblogic.
During production launch, another problem found. It seems that IIS proxy 5.1
plug-in with Weblogic 6.1 does not support the sticky load balancing. A sticky
service is one where a client sends its requests to the same instance and those
requests are not redirected to other instances. In production, two IIS match with
two Weblogic. Below is
#WebLogicHost=10.0.3.12
#WebLogicPort=8012
WebLogicCluster=10.0.3.12:8012,10.0.3.13:8012
COnnectionTimeoutSecs=10
ConnectionRetrySecs=2
ErrorPage=https://www.xxxx.com/eBank/sysnotready.htm
CookieName=eBankingWebLogicSession
Anyone have idea on out case?
Thanks,
KAI

My test was with 6.1 SP3.
The way to tell is by analyzing the cookie(JSESSIONID).
Perhaps the behaviour changed post SP1. I can't say for sure.

Is that entirely true concerning you don't need the persistence set to
replicated in the weblogic.xml to gain sticky load balancing?
The reason I ask was that in our situation sticky wouldn't work without
having the persistence set to replicated. This was with NSAPI and WLS 6.1
SP1. The weblogic servers were configured in a weblogic cluster. So..based
on this statement we should not have needed to set the persistence, but in
practice we did for it to work.
Gary
"Eric Gross" <[email protected]> wrote in message
news:[email protected]...
I just checked, and you are correct. You just need to have clustering
enabled in 6.1. You do not necessarily need to have persistence set to
replicated.
Of course, you won't get failover, but you will get the sticky load
balancing.

Why do we need to set session persistence to replicate in order to
perform
sticky load balancing ? There is no such requirement in WebLogic 5.1.
As
far
as I know, the IIS plugin simply interprets the value of the sessioncookie,
which should be embedded with the application server address, then
forward
the request to that particular application server.
We didn't use session replication in our environment because not allsession
variables are serializable.
"Eric Gross" <[email protected]> wrote in message
news:[email protected]...
The problem you mentionned in the other newsgroup post has been
fixed
and
will be in SP4. If you are in production or nearing production and
need
a
resolution now, then please open a case with support.
You should not need any other parameters to do the load balancing.
But
to
have the sticky load balancing, you must make sure you have session
persistence set to replicated for the webapp in question.
I'm not sure I am understanding your 3rd question.
In any case, my advice is to either wait for SP4 to bereleased(scheduled
sometime this month) or if you really need to go into production
soon,
contact support to obtain the latest IIS plugin.

Dear Eric,
Thanks very much for you kindly information, but we still have thefollowing issues
regarding the WL IIS proxy:
1. We have already tried the IIS proxy that comes with WL6.1 SP3.However, the
result from that version of IIS proxy is not satisfactory, as weexperienced cases
where the web page is not displayed correctly (as in
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.develo
per.interest.plug-in&item=994&utag=).
If there is any IIS proxy released after WL6.1 SP3, Could you
kindly
give
us
a pointer to the plugin?
2. In WL5.1 case, we are only required to have "WebLogicCluster"
parameter
set
to two weblogic servers in order use the load balancing features.
In
WL6.1, we
do not come across any additional settings required to support
load
balancing.
Is there any such settings required (e.g. in
config.xml,weblogic.xml,
application.xml,
etc?)
3. Does WL IIS proxy problem has anything to do with the version
of
the
IIS server/windows
versions that are using? we have already tried with IIS4 and IIS5
and
have
different
kinds of issues.
Thanks in advance for your kind assistance.

Does XI support Socket communication?

Hi,
This question came from our customers and consultants.
I saw the definition of socket in Wikipedia that it is somehow based on TCP, UDP. So far as I know, XI does not "support" TCP/IP. Does this mean XI does not support Socket either? Or this could be covered in the adapters of XI?
If XI does not support this, do you have any experience of a solution to socket communication?
Thanks in advance!
best regards
Jing

Hi,
sorry for the late reply.
I understand you that PI does not quite meet healthcare specific requirements.
Regrading medical equipment with PI, I am not familiar with that part.
But I have good news regarding HL7 protocol with PI. In the meantime we (SAP) have a service solution of HL7 adapter for PI, that supports HL7 communications based on HL7 message format/protocol.
Details please see this blog from Vijendra: http://scn.sap.com/docs/DOC-3891
hope this helps you.

PAC file support for Proxy Servers

When will AIR support PAC files for proxy servers?
In our network, we can't point to a PAC file because the AIR app simply ignores it, and we experience comms issues because of it. The workaround is to configure the network settings to point directly at the proxy, bypassing the PAC file.
This is a big problem as pointing directly at the proxy means a lot of manual configuration for each user that requires the use of the AIR app.
Any clues or suggestions?

Hi,
Additional configurations (DHCP and DNS) are required when you use Automatically detect settings.
For details, please refer to:

Proxy servers supported by different SAP EP version

Hi gurus ,
can anyone provide me deatails where to find information about
what are the different proxy servers that are supported by SAP EP 7.01 , 7.02 and 7.3
Thanks for your replies

SAP WebDispatcher would work as proxy server and the supported versions are specified in Link: [908097 - SAP Web Dispatcher: Released releases and applying patches|http://service.sap.com/sap/support/notes/908097]. Also check Link: [538405 - Composite SAP Note: SAP Web Dispatcher|http://service.sap.com/sap/support/notes/538405]. I hope you know WebD would do reverse proxy work as well.

Getting through proxy servers

Hello,

to connect through proxy servers? In other words, does Flash read

connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the
