I have successfully configured my SWT Browser application to use the proxy by setting VM arguments -Dnetwork.proxy_host and -Dnetwork.proxy_port to the according values.
However the proxy needs authentication, but the username / password prompt does not open. Futhermore when registering an authentication listener, the listener is never triggered.
The problems occured with a Linux Debian 64 Bit distribution. When compiling the same application for windows, all works fine, i.e. the password promt opens. The SWT Browser is configured to use MOZILLA, not WEBKIT. Unfortunatelly I cannot test with WEBKIT as I am limited to a given environment.
Temp solution: When starting the Linux Mozilla Browser, the prompt comes up. If entering there correct values and afterwards starting the SWT Browser application, then no authentication is needed at all and internet access is possible. But this is not a good solution.
When I register a location listener with "addLocationListener" to look whats going on with url calls, then I can see that the initial url (for example www.google.de) results to call a certain http site of the proxy server. And this http site is a redirect to a https site of the proxy. Then the https site results in calling the http redirect page again. This is then an endless loop.
I would guess that somewhere in the JAVA code of the SWT Browser class there is a routine that calls setUrl with those pages (what results in an
endless loop) and skip to call any authentication listener for some reason.
Maybe someone has an idea whats going wrong in this authentication process?
I have no solution but a hint: I'm not sure what you mean by "Linux Mozilla Browser" - I know Firefox and Xulrunner. But your workaround suggests that profile information is shared somehow and that shouldn't happen.
I tried to find some information how to define the profile (where the web browser keeps its cache, config, SSL certificates, plugins, ...) but to no avail.
This entry in the FAQ shows how to set the proxy host: How do I set a proxy for the Browser to use?
Try to find a way to add the user/password information into the request sent to the proxy server. If that fails, create a local proxy which connects to the real proxy as upstream and which can authenticate itself.
Looking at the bug database, there is no support for Browser profiles: Flexible Mozilla profile support - new API request

I'm trying to build an hotspot with mikrotik to allow the internet to my clients! So, the problem starts when i'm trying to access sites with Https sercurity like facebook, before the user authenticates.
With normal http connection the hotspot works fine, but when i put https, i'm getting this error: error
Can someone please help me? I have read all the docs in the mikrotik forum, nothing worked!
it's good news that nothing worked because it's the purpose of HTTPS: ensure that the site you want is the site you get. Hotspot does exactly the reverse: you ask for a website and you get another one (hotspot landing page): error.
There is no workaround without installing your certificate on each client, which is not doable on a hotspot environment.
Hopefully, problem has been handled with CNAs (Captive Network Assistants) which detect hotspot presence and launch an automatic HTTP request before the user has time to launch its own browser and navigate to Facebook. Latest iOS/Android/Windows versions do that automatically.
after upgrading to Safari 9 I'm getting this error in the browser:
[Warning] [blocked] The page at https://localhost:8443/login was not allowed to run insecure content from http://localhost:8080/assets/static/script.js.
Anyone knows how to enable the running of insecure content on the new Safari?
According to the Apple support forums Safari does not allow you to disable the block on mixed content.
Though this is frustrating for usability in legitimate cases like yours, it seems to be part of their effort to force secure content serving / content serving best practices.
As a solution for you you can either upgrade the HTTP connection to HTTPS (which it seems you have done) or proxy your content through an HTTPS connection with an HTTPS-enabled service (or, in your case, port).
You can fix the HTTPS problem by using HTTPS locally with a self signed SSL certificate. Heroku has a great how-to article about generating one.
After setting up SSL on all of your development servers, you will still get an error loading the resource in Safari since an untrusted certificate is being used(self signed SSL certificates are not trusted by browsers by default because they cannot be verified with a trusted authority). To fix this, you can load the problematic URL in a new tab in Safari and the browser will prompt you to allow access. If you click "Show Certificate" in the prompt, there will be a checkbox in the certificate details view to "Always allow content from localhost". Checking this before allowing access will store the setting in Safari for the future. After allowing access just reload the page originally exhibiting a problem and you should be good to go.
This is a valid use case as a developer but please make sure you fully understand the security implications and risks you are adding to your system by making this change!
If like me you have
frontend on port1
backend on port2b
want to load script http://localhost:port1/app.js from http://localhost:port2/backendPage
I have found an easy workaround: simply redirect with http response all http://localhost:port2/localFrontend/*path to http://localhost:port1/*path from your backend server configuration.
Then you could load your script directly from http://localhost:port2/localFrontend/app.js instead of direct frontend url. (or you could configure a base url for all your resources)
This way, Safari will be able to load content from another domain/port without needing any https setup.
For me disabling the Website tracking i.e. uncheck the Prevent cross-site tracking worked.
I am developing a Rails application that uses SSL connection. I am currently using third party resources that are js and css files for implementing a map (OpenStreetMap) . I have already tried to import these resources (js and css) into my application, but the javascript code tries to access an external WMS via HTTP.
The problem is that Google Chrome is blocking access to third-party resources from HTTP when the application is in HTTPS.
So I disabled SSL on a certain pages of the application and tried to force the HTTP or HTTPS the way I desire.
Following this blog: http://www.simonecarletti.com/blog/2011/05/configuring-rails-3-https-ssl/ and it works.
But when I force the HTTP protocol to the page where these resources will be used using Google Chrome, it forces HTTPS connection causing infinite loop.
If I clear the Chrome cache (that have already accessed the same page with HTTPS) in order access it via HTTP it works. But if I have accessed a HTTPS page and try to access via HTTP, Chrome forces the HTTPS connection resulting in an infinite loop.
The question is: Is there something I can set in the request that causes Chrome to accept the connection?
Regards
I've been doing some research on this, and it turns out that turning on force_ssl = true on Rails 3 causes the app to send an HSTS header. There's a bit of information about it here: How to disable HTTP Strict Transport Security?
Essentially, the HSTS header tells Chrome (and Firefox) to access your site only through HTTPS for a specific amount of time.
So... the answer I have for you now is that you can clear your own HSTS setting by going to about:net-internals within your Chrome browser and removing the HSTS state.
I think the answers here can help you: Rails: activating SSL support gets Chrome confused
I'm working on a web application that uses the google earth plugin. Recently, a new requirement to have non-public users logon was added, which meant that some users were now using the site over https. Among the things that broke in testing were the custom placemark icons (They were working using http).
The icons are hosted on the same server which servers the page.
Here are the urls for each of the protocols.
http - http://localhost/Images/yellow.png
https - https://localhost/Images/yellow.png
I can follow that link and the image will appear as you would expect.
The images hrefs are declared as icon styles in dynamically generated kml.
I want to avoid loading the images over http because I think that will cause internet explorer to present the user with a mixed content warning.
How do I get the images to load properly while using https?
I have been wrestling with this myself -- the short answer is that this won't work. If the content is served off of an HTTPS site that generates any kind of error/prompt (authentication, invalid certificate, etc.) the plugin will simply not load the content.
Interestingly, the desktop client works fine and prompts the user for credentials if necessary. However, neither client will allow content to be served off of site with an untrusted certificate.
The only workaround that I have found is:
Use a trusted HTTPS certificate on the server hosting the content (either trust the certificate on the client systems or just use a real certificate.)
Do not use HTTPS basic auth as that will always generate 401/Challenge responses which the web browser client will simply ignore
If authentication is a requirement, use NTLM authentication and common (e.g., domain) logins. If you load the plugin in Interent Explorer (or in a .NET WebBrowserControl) the authentication will be handled properly and the images will show up.
I was at a Google Earth administrator's training last week and the trainer confirmed this "bug". It is supposed to be fixed in the next version of the plugin (it may actually be fixed already -- what version of the plugin are you using?)
Sorry for posting basic question but please give me your advise.
I have to write iOS application which communicates with web application deployed on Tomcat server.
The web application requires client-app to call the "logon" servlet with username and password to get JSESSIONID. Once client get JSESSIONID, the web application allows to invoke other servlets.
But I couldn't figure out how to manage the session to invoke these servlets.
Would you please introduce me the examples/tutorials to learn how to invoke these kind of servlets?
Thank you in advance.
Here's a decent example of making an http request from iOS:
iOS: How to make a secure HTTPS connection to pass credentials?
There's nothing magic about making the call to a j2ee tomcat server - it's just an HTTP request, so any way you can make an HTTP request will work for you.
Maybe this one too:

edit: ahh, looks like this is the one you want:

The JSESSIONID is nothing special. If your application is set up to handle cookies coming back from your HTTP request then the JSESSIONID will come back as a cookie in the header. Otherwise you will be issued a redirect to a URL with the JSESSIONID in it. From there, if you handle cookies, the JSESSIONID will be passed automatically with each request with all of the other cookies. Otherwise you'll have to put it into the URL of each request manually.
Download the liveheaders plugin for Firefox and try hitting your servlet with the webbrowser and you can see how the JSESSIONID gets passed around. Next, turn off cookies in Firefox and you can see how it's passed around in the URL and you can see the redirect that Tomcat issues if you watch the headers in liveheaders.
