We have a company proxy (ip:port) and need to send HTTP POST with json payload to the URL like "http://server1.smthng.com/foo". Locally, name could not be resolved, but it is resolved at proxy. I dont understand how to configure haproxy to use proxy "ip:port" and send request without modifying the original URL.
I've tried curl to "http://server1.smthng.com/foo" after setting https_proxy variable from CLI (in linux) and it worked for me, so now I need to replicate same via haproxy.
From curl logs I could see that it first makes a CONNECT to proxy and once connection is there it POSTs the data.
I could be missing some knowledge here regarding tcp tunnels and the answer could be simple really. Anyway, need help.
The question is to be closed with no asnwer. The solution we took is via civetweb htt_proxy parameters.

I use WildFly behind an AWS load balancer. I want the Undertow server in WildFly to redirect http traffic to https, and I can do this mostly successfully with the following line placed in undertow-handlers.conf:
equals('http', %{i,X-Forwarded-Proto}) -> redirect(https://app.server.com%U)
Thanks to these folks for getting me this far! Now here's my desired tweak. Sometimes I run my web application behind a testing load balancer using 'dev.server.com' and sometimes I run it behind a production load balancer using 'app.server.com.' Currently, I have to remember to manually edit undertow-handlers.conf any time I switch balancers. I'm hoping there is a way to change the hard-coded 'dev' and 'app' to something mechanical. Is there a way to tell Undertow to just use the domain name that was originally requested?
Thanks.
Thankfully the undertow configuration gives you access to the request headers via Exchange Attributes, which you're already using to access the X-Forwarded-Proto header. So the solution is to simply use the Host header from the request like so:
equals('http', %{i,X-Forwarded-Proto}) -> redirect(https://%{i,Host}%U)
If you want to keep it as part of the deployment try using the %h in the redirect expressions. For example:
equals('http', %{i,X-Forwarded-Proto}) -> redirect(https://%h%U)
Another option would be to configure the server to handle the redirect for you. The CLI commands would look something like the following assuming the default ports of 8080 for http and 8443 for https.
/subsystem=undertow/configuration=filter/rewrite=http-to-https:add(redirect=true, target="https://%h:8443%U")
/subsystem=undertow/server=default-server/host=default-host/filter-ref=http-to-https:add(predicate="equals(%p, 8080)")
You can see all the possible exchange attributes in the Undertow documentation.
I have setup serverend points they work for the web interface fine but the api endpoint for my for app do not even give a error and does not time out.
I have tried turn the app to production mode in the web interfaces no joy.
I look at the doc for server setup but can find any thing to help.
So I would think their is configure issue where should I look?
On localhost ever thing works.
On remote host where using 168.192.0.15:8530 only web interface works not my api form either curl or may app
Without further information I can only guess what the problem is, but I'll try:
The default --server.endpoint configuration value for an ArangoDB server is tcp://127.0.0.1:8529. That means you will be able to access it from the local machine but not from other hosts.
To make the server respond to HTTP requests originated from other hosts, you will need to use an endpoint that includes the server's IP address as used in your network, e.g. tcp://192.168.173.13:8529 and restart it with the adjusted configuration.
If that's not working either, can you trying calling the target URL from another server via curl and check the server's HTTP response code. This might reveal the source of the problem, too. Note that you should invoke curl with the option --dump - to see the HTTP response code. For example:
curl -X GET --dump - http://192.168.173.13:8529/your/app
If that is not producing any results (i.e. no response at all), you might have a firewall in between that blocks requests. Probably you need to allow access on the port ArangoDB uses (8529 by default and used in my example).
So I have learn the issue is the api endpoint url is not the same on localhost at their are from outside. Example:
curl -X GET --dump - http://localhost:8529/broad/broad/login
curl -X GET --dump - http://192.168.0.15:8530/_db/_system/broad/broad/login

This lead me to my answer
My company uses PAC file to restrict any outgoing traffic through proxy server. The problem is, a lot of software does not provide the option to 'use IE setting', so that they cannot be connected to the internet.
I checked this PAC file up and found the right proxy server. But after I tried to use the proxy setting for these IE-unfriendly software, they still cannot get online. I used chrome to capture some packages and found the http header containing some Negotiation data. So I assume this proxy server uses some auto login mechanism like NTLM or kerberos.
But after I downloaded the famous Proxifier and tried to reroute the net traffic for some software, NTLM method did not work. I get the 502 error. Bummer...
Any hero comes to help! Am I thinking in the wrong way? Merci beacoup!
This is not a programming question but, did you try
cntlm (http://cntlm.sourceforge.net/) or
ntlmaps (http://ntlmaps.sourceforge.net/)?
Hope this helps
I have a php script that run perfectly when requested by the browser (example):
http://www.kwiksher.com/k3Serial.php?key="XXXXX"
in this case, I get the information of an user with the key XXXXX, which is the expected behavior.
However, inside my Photoshop plugin, I must to call it via socket, having to force a port in the connection:
http://www.kwiksher.com:80/k3Serial.php?key="XXXXX"
Doing that, I get the the content of Azure default 404 page (it is not even my customized 404 page).
If I use the same call (with the port added to the domain) on a browser, it works fine as well.
Any idea on how to fix it? I tried to flushDNS on my machine as well without success.
Thanks a lot,
Alex
It's likely that the socket library won't be using HTTP and therefore isn't sending a host header and the web tier on Azure can't actually figure out which Website it should serve the content from.
As you using this with a plug-in perhaps try and use the default hostname issued by Azure instead of a custom domain.
I am implementing XMPP service in the browser using BOSH. I use JAXL library. I am able to manage the connection over BOSH to my localhost server (ejabberd). The session is started and the user is authenticated with no problem. However, when I just change the BOSH host to jappix.com, the very first response from the server is only empty body. Even if I repeat the request (according to XEP-206) I still get only empty body so I'm unable to perform any other actions.
So that's my question: Is it possible to use jappix.com to handle my BOSH requests? Are there any limitations? How can I fix this issue? I'll provide more information if needed.
I am the Jappix.com owner!
Your question does not concern our service directly but more likely a node-xmpp-bosh - the BOSH server we are running - bug (?) that you can report on http://code.google.com/p/node-xmpp-bosh/
