Hi All,
I had a non appserver related question
I am trying to access a HTTPS URL from my client socket . This URL is
external to Sun, on regular internet, I am able to lookup from browser
fine, but when I open a URLConnection to it,I get following exception,
I set proxy as follows:
System.setProperty("https.proxyHost", proxyHost);
System.setProperty("https.proxyPort", proxyPort);
URL url = new URL(secureURL);
URLConnection conn = url.openConnection();
java.io.IOException: Unable to tunnel through proxy. Proxy returns
"HTTP/1.1 400 Bad request"
A search for "jsse proxy" came up a few helpful links.
According to:
http://archives.java.sun.com/cgi-bin/wa?A2=ind0009&L=java-security&P=7090
this seems to be a known JSSE issue:
Yesterday I sent the message below describing a problem I am having
and I believe I have some additional information. It looks like the
JSSE proxy code is expecting the response protocol and version to
match the request's protocol and version exactly. JSSE sends a
"CONNECT host:port HTTP/1.0" and expects HTTP/1.0 200 " but my MS
Proxy is returning "HTTP/1.1 200 Connection established" the response
minor version does not match the request minor version. If I am
interpreting the HTTP 1.1 standard correctly the proxy response must
have the same major version but it doesn't require
the same minor version, which would imply this is a bug in the JSSE
HTTP protocol layer.
This tech tip:
http://www.javaworld.com/javaworld/javatips/jw-javatip111.html
offers a workaround:
The Java Secure Socket Extension (JSSE) library from Sun Microsystems
lets you access a secure Web server from behind a firewall via proxy
tunneling. To do this, the JSSE application needs to set the
https.ProxyHost and https.ProxyPort system properties. The tunneling
code in JSSE checks for "HTTP 1.0" in the proxy's response. If your
proxy, like many, returns "HTTP 1.1", you will get an IOException. In
this case, you need to implement your own HTTPS tunneling protocol.
Which version of JSSE are you using?

Hello,
Is Maven2 able to do https connects over http proxies (for this it needs
to send HTTP CONNECT to the proxy)?
