HTTP + HTTPS Relay Proxy Server
Hello all,
I've found numerous tutorials on how to create a regular HTTP Proxy but there is nothing out there that at least hints on how to relay or forward HTTPS .
The idea is simple:
Client (Firefox browser) <-> HTTP(s) Proxy Server(that I want to write) <-> Internet Site
http requests are going through just fine, but once I go to https://www.something.com - game over :(
any advice on where to start ?
from lots of reading i figured out that i need 2 things:
HttpsRequestHeader
Tunnel out;
Tunnel in;
p.s.
your reply was very helpful .............

Help needed for CORBA over Http through proxy server[Very Urgent]
Hi Friendz,
I am new to J2EE. Right now I am learning RMI, Corba now.
In RMI, to pass through Http to bypass firewall or through proxy sever, we can use either Http to port or Http to CGI/Servlet i.e., Http tunneling.
In the same, I am running a simple corba application, i want my corba application to pass through my proxy server using http which is configured to address 127.0.0.1 and port 8118.
How to pass my corba application through proxy server. please help me and it is very urgent.
Is it possible or not, please let me know some comments about this topic
Thanks in advance Friends for your helpThis is so extremely urgent that it needs to be asked multiple times.

Connect to Server HTTPs through Proxy Server Problem
I am trying to connect through a company proxy via port 8080 to a https connection on a server so that it can mount on a desktop. Using 10.4.11 on Mac Pro
The connection works http through the company network and works http and https through my home network. The company require we use secure connections or something they will supply which will be out of date and clunky to use. I am using FullSwitch as a workflow so need the volume to mount.
Basically I do the following:
Go
Connect to Server
type address https://??????????????????/???????
I then get a Proxy Auth where I put my domain, user name and password
A certificate is then returned and I press continue
It then attempts to pass through the proxy tunnel to connect but just keeps going and going......
It should come up at this point with the server login but it doesn't
We are told by the IT team which only supports PCs that it is then that the Mac tries to create 2000+ connections but doesn't just creates lots of network traffic.
In between us and the proxy we sit behind a firewall but are told that there are no rules to stop https etc. I can connect to the site through Safari via https but as I need to upload files I need to be able to mount via https as a volume
Are there any suggestions as to what the issue may be or questions that I can try and ask IT to gather more info?
Many thanksMany thanks for your reply. We can use ftp but can not tunnel sftp through the proxy.
As I use fullswitch for automation I would like to keep the simplicity of mounting the server as files can be uploaded easily. Currently using http no problems but am being forced to use https from IT Security and of course being in a large corporation with only 35 Macs they say they don't support Macs and hey you have to do it our way or else. Driving me mad.
Sorry for going off on one but it is so frustrating as the supplier we are sending to wants the files the way we currently send them as they have their system workflow but my company wants us to use their sftp system that is clunky for in and out going file connections forcing suppliers to go to our sftp servers and not us supplying to them.....................
Right then I currently use Transmit with Type 7 on the proxy type for FTPing files using FTP Protocol not SFTP and have no problems going to the sites we have asked to get specific access to (again takes 2-14 days to get all the firewall rules changed to allow access to new ftp sites we are given, very efficient working practice)
So as you can see I really want to get the https working as it is the best option for workflow if IT security want us to secure.
Many thanks, again sorry for my ranting -

Sujith VargheseHi Varghese,
Reading the thread I am able to make out u r facing the same problem as I do.
current scenario#1:
Machine#1 client (using URLConnection("https://...") ----> Machine#2 (Server https port)
what I want scenario#2
Machine#3 client (using URLConnection("https://...") ---> Machine#1 (Proxy for https)----> Machine#2 (Server https port)
In scenario#1
- I have a Client machine at Location#1 which can connect to on Location#2
- I only have SSH connection to machine at Location#1
now this scenario#2 is what I would like to run so that
- I am able to connect to mc#2 at loc#2 from a machine at loc#3 with mc#3
- effectively starting a https proxy at location number mc#1 at loc#1.
Hope that clears the problem domain.
any help will be greatly appreciated.

Help! I was cruzing along just fine and went out tonight only to receive the message above:
Cannot open Page
Safari cannot open the page
The error was: "There was a problem communicating with the web proxy server (HTTP)."
I have had all the Apple iPhone phone. Have never encountered anything like this.
All systems are GO as soon as I log on to wifi.
Can anyone help, please.I am also fixed. I also loaded Onavo, but that was the other day ... this is what I did with the help of online chat with AT&T ...
I went to:
Settings
Wifi
I selected the network I was working on by hitting the blue arrow located on right side
At the detail page of that network I scolled down to the bottom to find HTTP Proxy boxes
I was on Off and changed it to Auto and it worked!
I was soo jazzed!!
Instructions said if it was already on AUTO, to change it to Manual and make your Port = 80 but I didn't have to do that!
YIPPIE!! I'm a new man!!
Go to settings -----> WI-FI -----> select the network you're using ------> hit the blue arrow located on the right-side of the network name (ie: show details of that network), this takes you to another page.
--------> at the bottom of the page you'll see "HTTP Proxy" boxes (located below the "renew lease" button) ---------------> change the proxy to AUTO. Note: if you're already at AUTO, change it to "Manual" and make your Port = 80. -
How do I send HTTP request to a server via a proxy server in JDK 1.4?
JDK 1.5 's URL class provides an overloaded version of openConnection() which accepts an object of type Proxy using which we can establish connection with a remote server via a proxy server, but JDK 1.4 doesn't provide any such overloaded version. How do I do that in JDK 1.4? Even if I had a class that can create HTTP packets for me, then I could have established Socket connection with the proxy server and sent the HTTP packet to it. Is there a way to do that also?
There are some system properties, which can be set with System.setProperty [http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html]

Hi,
It works very well. I have experienced this model for a distant Forte client
calling a Forte Server service Object for instance without any environment
and without TCP access (passing through firewall for instance).
It has also worked very well to make an injectot to improve Web Enterprise
and IIS using the SendRequest from HTTPAccess.

this is available in L.x on....
There is api documentation in M.2 (with scant
examples.)
There's a special process to put the project in your
repository (it isn't installed in the repository in
the standard install,) the documentation in M.2
(probably in M.0 too, AFAIK) that tells you how to do
this (look for HTTP-DC in the online help.)
I haven't done much with it yet, I've just installed

great. I'll try to contribute more the moment I get a

Does the plugin-in still not work with HTTPS and a proxy server?
From plug-in docs -
"Java Plug-in supports http, ftp, gopher and SOCKS v4 protocols through the proxy server. Currently, Java Plug-in does not support https (SSL). "Hello
I am making HTTPS calls from within my applet code and this works fine using the basic Java Plug-in support for HTTPS.
This means my code basically does:
URL url = new URL("https://myhost.com/servlet/Test");
URLConnection conn = url.openConnection();
etc..
We are using Java 1.4.2. I've read in the "How HTTPS Works in Java Plug-in" for 1.3, that the plugin uses the browsers API for making HTTPS connections. Is this still the case for 1.4?
My basic problem is that it all works fine if the browser is NOT configured to use a proxy server. If a proxy server is configured we get the following Exception in the client:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request ( The data is invalid. )"
I have read that "Sun's Java Secure Socket Extension (JSSE) library allows you to access a secure Web server from behind a firewall via proxy tunnelling. However, JSSE expects the proxy's reply to the tunnelling request to begin with "HTTP 1.0"; otherwise, it throws an IOException" (http://www.javaworld.com/javatips/jw-javatip111_p.html)
The article talks about using the JSSE library but it seems to be assuming the client is an application not an applet.
How do I use JSSE from within an applet if all the proxy information I seem to need to set in the JSSE code is held by the browser?
Will JSSE support proxies returning responses beginning HTTP 1.1 in the future?
Any help on this would be greatly appreciated.
Many thanks

Configuring the application server to use HTTP proxy server
Hi,
I am trying to configure LiveCycle ES2 to access services over the internet and since my Livecycle server connects to internet through a Proxy server, I have referred to section 5.8.2 of LiveCycle install_weblogic.pdf that states the following:
If the computer that LiveCycle ES2 is running on uses proxy settings to access external web sites, the
application server should be started with the following values set as Java virtual machine (JVM)
arguments:
-Dhttp.proxyHost= [server host]
-Dhttp.proxyPort= [server port]
However, I am getting the below exception while running the LC application as my Proxy server requires User credentials to connect to the internet:
weblogic.net.http.HttpUnauthorizedException: Proxy or Server Authentication Required.
I tried providing the below JVM startup argument too, but no luck:
-Dhttp.proxyUser= [proxy user]
-DhttpPassword= [Proxy password]
Can you please suggest how to configure User credentials for the Proxy server in Livecycle.
Thanks in advance.Hi WASIL,
Thank you for your response.
I have followed the above document suggested by yourself and the relevant steps while setting up the Server and the Workbench, and verified the settings too.
The installation guide does highlight the steps to configure a Proxy server. However, the guide does not mention anything about how to handle Proxy server authentication.
Please note that there are Proxy authenication options available in Workbench to configure how the Workbench connects to the LiveCycle server, whereas the problem I am facing here is how to connect the LiveCycle server with internet services through a Proxy server.
I hope that clears the problem statement.
Thankyou for your assistance. -
Http proxy server connetion error
please help me
i have built a proxy server between iis and client
client gets successfully connected to proxy but he is not abale to
retrive the pages stored on iis
error produeced is : Server not found - UnknowException java.net
client get error message as : 404 required page not found
my email address is : [email protected]
thanks in advanceHere is a java HTTP server you can use instead of IIS (comes from the burrowing through firewalls article). This class allways sends the same response to any request on port 80 but it should be a good tool to test your proxy server (as to what requests the proxy sends and if the proxy pickes up the response).
Stop IIS on the IIS pc and run the following class:

we have installed weblogic5.1 in two machines one in NT and the other in windows98.
We want to use one as the webserver and the other as the proxy webserver. When
ever if a particular file is not found in the webserver it should automatically
redirect to the proxy server. we have configured the following set of lines in

which is not in the webserver and located in the proxy webserver it searches only
in the webserver and giving the "404 not found error". What further configuration
we have to do to achieve this. Both systems are in the network.

Redirecting http traffic to the proxy server
Hi,
We have a requirement to divert web traffic to blue coat proxy through firewall. Below is the setup
Requirement:
We need to divert web traffic from 10.20.200.0/23 [DMZ-STAFFNET] and point it to Bluecoat proxy to process the packets.
Now that ASA doesn't support PBR to accomplish this, how can we accomplish this ?Hi,
To list one limitation that you might see in your scenario , You would only be able to redirect the subnets to the proxy from those subnets which are physically behind the interface where the WCCP server resides only. i.e. UNTRUST
Now , talking about the NAT , why don't you try this NAT if you don't want to NAT the Source part of the Traffic:-
(DMZ-STAFFNET) to (bluecoat) source static DMZ-STAFFNET DMZ-STAFFNET destination static internet proxy-server service original-http proxy-8080
Also , ASA now supports Policy Based routing from ASA 9.4.1 :)

Although if i switch off proxy server everything works perfect (both HTTP and HTTPS web-services).
What could be the problem with?Hi Kenneth,
At the moment, SALT does not support the configuring of an outbound proxy server. I suspect you could use a transparent proxy server, i.e., a proxy server/router combination that proxies outgoing requests, although this isn't something we have tested. My suggestion would be to open a support case and ask for this enhancement. I think it is a reasonable thing for SALT to support.

HTTP connection from OSB web service to external system via a Proxy Server
Dear experts,
May I know has anyone tried to use HTTP protocol to send a request from OSB web service to external system via a proxy server? Heard that we need to establish some sort of tunnel (socket) to talk to Proxy Server. Can you please any have sample code or configuration steps to share?

Adding Proxy Servers
Use the Summary of Proxy Servers page to add and configure Proxy Server resources and make them available in Oracle Service Bus as a system resource. You must be in an active session to configure or reconfigure Proxy Server resources.
1. If you have not already done so, click Create to create a new session or click Edit to enter an existing session. See Using the Change Center.
2. Select System Administration > Proxy Servers.
3. Click Add.
4. In the Name field, enter a name for the Proxy Server resource. This is a required field.
5. In the Description field, enter a short description for the Proxy Server resource.
6. In the Host-Port Parameters section, enter the following information:
1. In the Server Host field, enter the host name or IP address of the Proxy Server. This is a required field.
The Server Host name for the Oracle Service Bus proxy server must be identical to the server host name of the actual proxy server.
2. In the Clear Text Port field, enter the Proxy Server clear-text port number.
3. In the SSL Port field, enter the Proxy Server SSL port number. You must enter either a clear text or SSL port number.
4. Click Add.
You can configure multiple Proxy Servers for each Proxy Server resource. This enables Oracle Service Bus to perform load balancing and offer fault tolerance features for the Proxy Server resource.
7. If the Proxy Server performs proxy authentication, enter a user name in the User Name field, and the associated password in the Password and Confirm Password fields.
These fields are optional, and required only if the Proxy Server is secured.
8. Click Save to create and save the Proxy Server resource in the current session.
9. To end the session and deploy the configuration to the run time, click Activate under Change Center.
