  • redirecting in node.js behind mod_rewrite proxy

    - by chmanie
    I have a node.js application running behind an Apache mod_rewrite proxy configured in a .htaccess file like this: RewriteCond %{HTTP_HOST} =mydomain.com [OR] RewriteCond %{HTTP_HOST} =www.mydomain.com RewriteRule (.*) http://localhost:3000/$1 [QSA,P] When I now do a redirect (e.g. express' res.redirect()) inside my node.js application (which runs on port 3000), the user is always redirected to http://localhost:3000/ (which is in fact exactly what is defined above but not the desired behaviour). Is there any way around this?

  • Principles of an extensible data proxy

    - by Wesley
    There is a growing industry now with more than 30 companies playing in the Backend-As-A-Service (BaaS) market. The principle is simple: give companies a secure way of exposing data housed on premises and behind the firewall publicly. This can include database data, as well as Legacy PC data through established connectors; SAP for example provides a connector for transacting with their legacy systems. Early attempts were fixed providers for specific systems like SAP, IBM or Oracle, but the new breed is extensible, allowing Channel Partners and Consultants to build robust integration applications that can consume whatever data sources the client wants to expose. I just happen to be close to finishing a Cloud Based HTML5 application platform that provides robust integration services, and I would like to break ground on an extensible data proxy to complete the system. From what I can gather, I need to provide either an installable web service of some kind, or a Cloud service which the client can configure with VPN for interactions. Then I can build in connectors, which can be activated with a service account, and expose those transactions via web services of some kind (JSON, SOAP, etc). I can also provide a framework that allows people to build in their own connectors, and use some kind of schema to hook those connectors into the proxy. The end result is some kind of public facing web service that could securely be consumed by applications to show data through HTML5 on any device. My gut is, this isn't as hard as it sounds. Almost all of the 30+ companies (With more popping up almost weekly) have all come into existence in the last 18 months or so, which tells me either the root technology, or the skillset to create the technology is in abundance right now. Where should I start on this? Are there some open source projects I can leverage? A specific group of developers I can hire? I'm confident someone here can set me on the right path and save me some time. You don't see this many companies spring up this rapidly if they are all starting from scratch with proprietary technology. The Register: WTF is BaaS One Minute Video from Kony on their BaaS

  • Ubuntu 12.10 - WiFi keeps disconnecting (using a Proxy)

    - by semiogeny
    I just installed Ubuntu 12.10 on my Acer Aspire One Netbook and everything works excellent except for the WiFi. When I click on a network I get connected but only for about one minute and then it says 'Disconnected - You are offline' It tries to reconnect and after a while it says 'Connection Established' It's a school network which uses no authentication but a proxy (172.16.4.1:8080) Can anyone help me? I'm new to Ubuntu and don't know a thing. Thanks for your help :)

  • Validate an Xml file against a DTD with a proxy. C# 2.0

    - by Chris Dunaway
    I have looked at many examples for validating an XML file against a DTD, but have not found one that allows me to use a proxy. I have a cXml file as follows (abbreviated for display) which I wish to validate: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.018/InvoiceDetail.dtd"> <cXML payloadID="123456" timestamp="2009-12-10T10:05:30-06:00"> <!-- content snipped --> </cXML> I am trying to create a simple C# program to validate the xml against the DTD. I have tried code such as the following but cannot figure out how to get it to use a proxy: private static bool isValid = false; static void Main(string[] args) { try { XmlTextReader r = new XmlTextReader(args[0]); XmlReaderSettings settings = new XmlReaderSettings(); XmlDocument doc = new XmlDocument(); settings.ProhibitDtd = false; settings.ValidationType = ValidationType.DTD; settings.ValidationEventHandler += new ValidationEventHandler(v_ValidationEventHandler); XmlReader validator = XmlReader.Create(r, settings); while (validator.Read()) ; validator.Close(); // Check whether the document is valid or invalid. if (isValid) Console.WriteLine("Document is valid"); else Console.WriteLine("Document is invalid"); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } static void v_ValidationEventHandler(object sender, ValidationEventArgs e) { isValid = false; Console.WriteLine("Validation event\n" + e.Message); } The exception I receive is System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required. which occurs on the line while (validator.Read()) ; I know I can validate against a DTD locally, but I don't want to change the xml DOCTYPE since that is what the final form needs to be (this app is solely for diagnostic purposes). For more information about the cXML spec, you can go to cxml.org. I appreciate any assistance. Thanks

  • C# Proxy, what is the best way to do this?

    - by Kin
    I'm writing a proxy using .NET and C#. It has a couple of functions that it needs to fulfill. I haven't done much Socket programming, and I am not sure the best way to go about it. Should I use Synchronous Sockets, Asynchronous sockets? Please help! It must... Accept Connections from the client on two different ports, and be able to receive data on both ports at the same time. When a connection is made on a port, it must immediately connect to the server, and start sending data as it receives it from the client to the server. Packets must be forwarded in the order they are received, exactly as they were received. It needs to be as low latency as possible. I don't need the ability for multiple clients to use the proxy, but it would be a nice feature if its easy to implement.

  • can you use proxies to do load/stress testing on a server, with proxy serving as a sort of mirror?

    - by EndangeringSpecies
    suppose I want to test a server's and its web application's ability to handle many simultaneous connections well and show decent latency. So ideally I would want a thousand machines to bombard it with usage requests, but that's not practicable. So instead, can I just make a testing script with a thousand threads to run on the same server and have them perform the testing, connecting to the server via a geographically far-away proxy? My reasoning here is that the signal will have to travel realistically big distances to the proxy and back, so that sort of emulates the reality of real clients accessing the server. Then again, to take this one step further, are there prepackaged emulators/frameworks that could perform a similar test without using internet at all, just simulating the latency of the network, realistically creating all the socket connections and other resource intensive stuff etc?

  • Are there any sFTP clients that support a proxy that uses NTLM authentication?

    - by Iraklis
    The title pretty much summarizes the question. We have deployed an sFTP server that needs to be accessed from our client's MS Windows Pc's that reside within a restricted local area network. The only way they can get out for their Intranet is to use an HTTP proxy that requires NTLM authentication. From what I understand all open-source sFTP clients (FilleZilla,WinSCP,etc) do NOT support NTLM authentication (Because of legal issues). I know that there are workarounds to this (installing a local proxy at the machine that understands NTLM) but this would break all sorts of security policies of our client. So my question is : Does anyone know of any sFTP client that supports NTLM ?

  • How can I use a computer as a router and send all client traffic through anonymous proxies?

    - by Terrapin
    Is there a way that I can setup a spare box as a router on my network, and route client traffic through a proxy in order to hide my location? Specifically, I would like internet traffic to/from my Roku Box to be routed via proxy, but there is no proxy support built in to the Roku. So I would like wire my Roku directly my computer's second NIC, and force all traffic through a proxy. What kind of software and hardware setup will I need? Also, which anonymous proxy service are best for this purpose? I'm not interesting in full anonymity or encryption. I simply want to mask my location while providing the best possible throughput.

  • Does Basic User Authentication require 2-Phase communiation?

    - by RED SOFT ADAIR-StefanWoe
    My Application connects to the Internet to HTTP Services using boost::asio. Recently we added support for HTTP Proxys and Basic User Authentication. We implemented Basic User Authentication by just sending Authentication parameters with every HTTP call if a user configured a proxy in our program. Parameters are sent as described here: Authorization: Basic <base64 Encoded username:password> This works at least for one user and his proxy server. Other users report that their Proxy server replys with 407 Proxy Authentication Required My guess is that some proxy servers accept 1 one phase authentication and that others don't. I do not find any information that a 2 Phase communication is requested where the access always is denied for the first call by returning 407 and that only a second call is accepted. Our program yet does not retry the call if a 407 has been returned. Do we have to add this? I asked this question before on stackoverflow but did not get a sufficient answer.

  • Apache Balancing by source IP

    - by Daniel
    I am using Apache's Proxy Balancer to balance one sub domain (e.g. subdomain.domain.com) to an application which is located on 2 servers. Here an extract from my Apache configuration file: <Proxy *> Order deny,allow Allow from all </Proxy> <Proxy balancer://cluster1> BalancerMember http://server1:28081 route=w1 BalancerMember http://server2:28082 route=w2 </Proxy> ProxyPass /path balancer://cluster1/path ProxyPassReverse /path balancer://cluster1/path My question is, if it's possible to decide with the source IP-address which BalancerMember should be used for the request? To e.g. Requests from 1.2.3.4 to Member 1?

  • Using a custom form in a modelformset factory?

    - by jamida
    I'd like to be able to use a customized form in a modelformset_factory. For example: models.py class Author(models.Model): name = models.CharField() address = models.CharField() class AuthorForm(ModelForm): class Meta: model = Author views.py def test_render(request): myModelFormset = modelformset_factory(Author) items = Author.objects.all() formsetInstance = myModelFormset(queryset = items) return render_to_response('template',locals()) The above code works just fine, but note I'm NOT using AuthorForm. The question is how can I get the modelformset_factory to use the AuthorForm (which I plan to customize later) instead of making a default Author form?
