How to stop Quicktime using IE Proxy Settings

Hi there,
My company's Proxy Server (Microsft ISA Server) requires Windows Integrated authentication which Quicktime does not support so QT web access fails.
We have a Winsock Proxy component installed on the clent but for this to come into play we need to configure Quicktime not to use IE Proxy Settings as otherwise QT tries to talk to the Proxy server and cannot authenticate.
I have spent a number of hours looking into this but cannot find any way to do this. I know a lot of app's allow you to turn off using IE's Proxy settings and wanted to se if anyone knew how to do this with QT.
Thanks in advance for any help on this,

Why not just right-click and save the linked file to your computer?
Open the .mp3 with any app you choose.
You can disable the QuickTime plug-in from playing .mp3 files in a browser window by opening the QT Control Panel/Advanced and click the MIME Settings button. Remove the check mark for the .mp3 format and restart your browser for this change to take effect.

How do you apply the school proxy settings to the ipad to filter website searches?

How do you apply the school proxy settings to the ipad to filter website searches?

Hi Stebop1987,
You will want to apply a configuration profile with Global HTTP proxy settings to your proxy server. Use Apple Configurator or an MDM to deploy the configuration profile to your fleet of iPads. I recommend you contact your web filter provider for detials on what proxy details to enter in the configuration profile (type, server, port, username, password).
Hope this helps!

"Use system proxy settings" Not working on Mac OS X Snow Leopard

When I change the network location or when I select "Use system proxy settings" on the connetion configuration dialog.
Firefox is not using the proxy defined on the loction set on Mac OS X Snow Leopard.
I usualy change from work to home, at work I've a proxy and at home I don't, and it's a bit annoying to have to change the proxy twice a day. So I tryed this feature, but It's not working for me.
I've tryed also with Firefox 3.6 (I think) and didn't work either.

I run it from eclipse, and on debug mode i checked the value of
java.library.path, and it was ok.
Any way, how can i do what you suggested on mac?It's just a command line argument, but there's no reason to add it if your
java.library.path is ok. One of its componenents must be a directory where
your shared lib is stored, that's all. BTW, the Mac is unix based isn't it?
Shouldn't it be an .so file then? (just a wild guess)
kind regards,
Jos

I use the proxy settings add-on in Firefox to access my company server. However, I updated Firefox this morning to the latest version. Now this add-on doesn'tl.

I used the proxy settings add-on to access the company server and wi-fi with my Android 2.36 phone.
This morning I updated Firefox. The add-on doesn't work anymore. I uninstalled it and went to the add on website to reinstall what I thought must be a new version. This add-on doesn't seem to exist anymore.
How do I change proxy settings with the new version of Firefox for Android?

The author of the add-on will need to update their version to be compliant with our newly rewritten Firefox for Android product.
The new version of Firefox does not provide a user-interface for manipulating proxy settings.
On the other hand, you can manipulate these settings yourself at your own discretion by visiting the URL about:config and searching for network.proxy

Windows - Use system proxy settings not working as expected

Hi everyone,
I have a bit of an issue that I could use some help with. We currently have remote users that utilize an SSTP VPN connection to access our internal network. Once connected, those users are required to use an internal proxy server to connect to the Internet. The proxy server is Microsoft's TMG and utilized domain authentication.
On our remote Windows clients we have their Internet Options configured to utilize a proxy as follows:
Internet Options -> Connections -> LAN Settings -> No proxy configured at all
Internet Options -> Connections -> Highlight SSTP Connection -> Settings
Use a proxy server for this connection -> IP/Port of Proxy Server
Firefox and Chrome are both configured to use system proxy settings.
Here is my process to demonstrate the issues:
Remote client workstation is rebooted.
With the above configuration just after a reboot, a remote user that is not connected to the VPN can browse the Internet with Internet Explorer, Chrome, and Firefox. None of the browsers prompt for credentials.
A remote VPN connection is then established.
FF is opened and HTTP connections utilize the proxy server. However, HTTPS connections do not use the proxy server, but instead attempt to use the default gateway. FF does not prompt for credentials. FF is closed.
Chrome is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. Chrome is closed.
IE is opened and can access both HTTP and HTTPS sites without issue. No credential prompt. IE is closed.
Here's where it gets weirder...
FF is then reopened. The VPN connection is still up. FF will prompt for credentials. Domain credentials are supplied and FF can now utilize the proxy for both HTTP and HTTPS connections. FF is closed.
VPN is disconnected.
FF is opened and cannot access the Internet as it is still trying to use the proxy server. FF is closed.
IE is opened and can access the Internet. IE is closed.
Chrome is opened and can access the Internet. Chrome is closed.
FF is reopened and can now access the Internet. FF is closed.
In summary, in the above scenario FF acts in an unexpected manner with regards to proxy usage when "use system proxy settings" is applied. However, Firefox begins acting as expected after IE is opened and closed. For example, connect to VPN, open IE, close IE, open FF, and everything works accordingly. Disconnect the VPN, open IE, close IE, open FF and everything works as expected.
Any insight you can provide would be appreciated as it is affecting our FF users and the sooner we can achieve resolution the better. As a note, we've also worked through this issue with WPAD and proxy auto-detect. I've intentionally removed these from the equation to simplify troubleshooting.
Thanks

Quick update. Added to a previously filed bug. Looks like it's assigned now so maybe we'll see a fix for this soon.

Firefox not detecting/using system proxy settings

I use a command line script to change among various proxies (and none). Firefox does not recognize when a proxy is turned on or fails to connect to it (no error messages), while other browsers and applications do just fine.
I have tried selecting "Use system proxy settings" and "Auto-detect proxy settings for this network."
My script contains these lines to activate a proxy
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v DefaultConnectionSettings /t REG_BINARY /d 46000000b10000000200000014000000736f636b733d3132372e302e302e313a313131311c0000002a2e6c6f63616c3b3139322e3136382e31312e2a3b3c6c6f63616c3e000000000000000000000000000000000000000000000000000000000000000000000000 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v MigrateProxy /t REG_DWORD /d 1 /f
The first line enables the proxy to take effect without entering inetcpl.cpl. Again, this works for any application other than Firefox.
The proxies are all through ssh with port forwarding.
I do not want to manually configure a proxy in Firefox, because I do not want to change this every time I need to change proxies or turn them off. This is not an acceptable solution.
I am on Windows 8.1 64bit, with Firefox version 35.0
Any idea what might be going on here?

Thank you for the response, but as above, the "Auto-detect proxy settings for this network." setting does not work.

Can lync client use internet proxy settings to proxy edge servers, if direct access is not reachable?

Hi everybody I am trying to Login with my lync Client out of my organization. So I am using lync as a remote user. I am in another organization, and I am using their coporate lan wired and wireless, but I cannot Login to lync in my organization.
I see that I cannot Access my edge Server on port 443 to authenticate directly, I know that Client in this organization use Internet Proxy to browse the Internet. they have a .pac in their ie Settings.
my question is; can lync Client use Internet Proxy Settings to reach the Destination? I mean the Access edge on port 443?
or it can use only Client direct Access to reach the edge Servers?
I Think that the answer is that I use tcp protocol and not http, and maybe that is the reason why I cannot use the Internet Explorer Proxy Settings to reach the Access edge Servers, different maybe is the case I Need to reach the reverse Proxy for live Meetings.
Hope my question is clear.
Thanks

Proxy settings are used to tell Internet Explorer the network address of an intermediary server (known as a proxy server) that is used between the browser and the Internet on some networks.
Lync client doesn’t use Internet Proxy Setting. You need to access the Edge service directly.

Use System Proxy Settings - when this is selected in FF v3.6.6, does it adhere to the same local IE proxy setting? We use a pac file configured in "Use automatic configuration script."

Does anyone know what Firefox looks at locally on the PC when the "Use System Proxy Settings" setting is selected? It appears to be the default setting, recently changed from "No Proxy" of versions past...
Our company uses a pac file specified in IE under "Use automatic configuration script" - with this new default, does it adhere to the same setting in:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

I may be wrong but I think that the "Use System Proxy Settings" makes sense only on Linux and generally speaking "other OSes". As far as I know there is no generic proxy settings in Windows operating system.
The one I know is in the registry part of Internet Explorer.
So in my understanding in Windows, Use System Proxy Settings = No Proxy

How do "Auto-detect proxy settings for this network" and "Use system proxy settings" work behind the scenes?

How can I see what the proxy firefox actually uses when I check either of these two options?
Does it take it from Internet Explorer?
Are they stored somewhere in the registry?

Hi conectionist,
This is taken if there is a proxy set up in your network settings on your OS. If you would like to test there may be an add on:

How to find the system's proxy settings programatically

Hi,
I am creating a ABAP class which acts as a HTTP client and thus I use the standard object "call method cl_http_client=>create_by_url". This method takes the proxy host and proxy port as input and i want to know how can I find the proxy settings of my system programatically so that I do not ask customers to add these values as configurations for my code.
Is there any standard API in ABAP to find this information?

How do i change my network proxy settings on iTunes?

Hi,
I've been using a certain proxy to connect to the iTunes store on my PC iTunes.
Now, the proxy details have changed, i already update the new details on the Internet Options (Windows Control Panel) and now i'm trying to update the proxy settings on iTunes. But it not prompting for a new one like before, and i think it because i selected remember passwword previously.
How do i reset these settings so i can enter the new proxy settings. iTunes keeps on telling me to check my network connection.
Thanks in advance.

Authorization
iTunes Store- Authorize or deauthorize your Mac or PC.
In iTunes you use the Authorize This Computer or De-authorize This Computer option under the Store menu in iTunes' menubar. For Windows use the ALT-S keys to access it. Or turn on Windows 7 and 8 iTunes menus: iTunes- Turning on iTunes menus in Windows 8 and 7.
Deauthorization
You can de-authorize individual computers, but only by using those computers. The only other option is to "de-authorize all" from your iTunes account.
1. Open iTunes on a computer
2. From the Store menu, select "View my Account..."
3. Sign in with your Apple ID and password.
4. Under "Computer Authorizations" select "De-authorize All".
5. Authorize each computer you still have, as you may require.
You may only do this once per year.
After you "de-authorize all" your authorized computers, re-authorize each one as required.
If you have de-authorized all computers and need to do it again, but your year has not elapsed, then contact: Apple - Support - iTunes - Contact Us.
For more information on authorization and de-authorization: iTunes Store- Authorize or deauthorize your Mac or PC.

Force iCloud to use network proxy settings.

It seems that iCloud does not use the system wide proxy settings. I am in college and we must use the authenticated system proxy, and iCloud has been unable to update since I have been here. How can I force it to use the authenticated protocol?

You need to talk to the IT people at your college. College ITs can do strange things at times, I know, I work at one (but mine is very good at supporting macs and all things mac).

How Can I pre-configure the proxy settings in Acrobat 8?

We use a proxy server to authenticate users and it's causing a problem for our e-licensing. Is there a place to pre-configure the proxy settings / login and password for the e-licensing to happen quietly so our users don't have to see it?

Have you searched the forum for proxy? I do not have an answer, but this has been discussed before. I am not sure there is an answer in the discussions, but it is worth a try. There is likely a knowledgebase article on the issue also. Good luck.

ML Server: How do i push my school proxy settings to our ML clients?

I'm in profile manager and can see the option for proxy settings when using wifi, but we dont want to use wifi we want to use ethernet only, of which the options then dissapears to entere proxy details!!
Can someone please help solve this ridiculous problem apple have created
Thanks

The best way to do this is to use a feature invented by Microsoft (gasp!). Microsoft invented something called 'Web Proxy Autodiscovery' (WPAD). With this setup on your network the computers both Windows and Mac can 'autodiscover' the presence of a proxy server and the settings needed to use it.
Originally, OS X could not use WPAD, however I (yes moi) was able to persuade Apple to add support for this and it is available in Snow Leopard (10.6), Lion, (10.7), and Mountain Lion (10.8). You can turn it on by opening System Preferences, clicking on the Network icon, selecting Ethernet interface on the left, unlocking the padlock at the bottom, then clicking on the Advanced... button on the right, and then going to the Proxies tab at the top. You need to turn on only 'Auto Proxy Discovery' option. You do not want to use Automatic Proxy Configuration.
There is one final step, WPAD can work in one of two different ways, it can either provide the settings via DHCP and point your computer to the address of the .pac (proxy auto config file), or it uses a sepcific webpage address based on your networks domain name (the DNS method). See http://en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol
I strongly recommend using the DHCP method. This requires setting your DHCP server up to advertise via the DHCP option code 252
It is possible to setup Apple's own DHCP server with a DHCP option code 252 but you need to manually edit the /etc/bootpd.plist file to do this. This ability to define DHCP option codes using Apple's DHCP server was added by Apple again in response to one of my suggestions. I have also written a utility to make it easier to generate the code you need for this.
Most DHCP servers built-in to routers cannot do DHCP option codes but Linux, Unix, Windows Server, and as mentioned above Apple Server all can.
