Proxy servers

I'm a teacher and have mini ipad with retina display and the apple tv. I would like to use airplay to project, but tech guy says can't set up wifi with proxy server because appletv doesn't allow??

That is correct.

Getting through proxy servers

Hello,
Does anyone know if the URLRequest / Loader classes are able
to connect through proxy servers? In other words, does Flash read
the PC's proxy configuration and automatically use it?
Also, I was wondering, if one was to create a Socket and then
connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the
Internet, would this
connection succeed or fail?
Thanks for your insight.
Dan

Proxy servers and the "cannot publish" error - v.1.1.2

Using the latest iWeb (1.1.2), attempts to publish my work to my .Mac account resulted in the infamous "publish error." I then came across this KB article:
http://docs.info.apple.com/article.html?artnum=303927
I turned off my proxy access in the Network settings, and voila, publishing was successful. But now, I'm circumventing my much-needed proxy.
It's been suggested in other threads here that proxies aren't a problem if one's iDisk is accessible through it. This is not the case. With the proxy, iDisk access is fine, it's only iWeb publishing that is a problem.
Any way to keep my proxy and still publish with .Mac?

iDisk access and iWeb publishing ARE indeed different activities. They are similar in that they both utilize the WebDAV protocol over Port 80, but they are different in their individual requirements for back and forth communications with the .Mac servers in terms of how soon or in what timeframe they expect to hear confirmation of transfer back from the server.
It is apparent to me that the network timeout threshold for copying something to iDisk is a lot longer than that for publishing through iWeb. In fact, I would say that iWeb has become a lot more stringent with network timeouts ever since it was updated from 1.0 to 1.1.
Anything in between your computer and the .Mac servers contributes to network latency. There are both software and hardware contributions to this latency. Proxy servers, like routers, can be software or hardware based. Software-based latency is most often greater than hardware-based latency.
I would guess that removing any kind of latency "generating" obstacles within your control would likely improve iWeb function and decrease the incidence of publish errors. Some of these obstacles can include background processes, busy LAN activity (like VOIP use or streaming music/video or online gaming), wireless access points, proxy servers, and routers.
On the other hand, I also think that if Apple increased iWeb's network timeout threshold, that most of the publishing errors that people experience could be eliminated.

OS X Tiger and proxy servers

At the office I use my MacBook Pro connected to an exchange server. To do so I've had to use Microsoft Entourage and Firefox. I cannot get any of the Mac software (iTunes, Safari, Mail, etc.) to work with the server.
I've read previous discussions in this forum on the subject but none have helped.
How can it be that Firefox can have the simple "auto-detect proxy settings for this network" that works and the 'ahead of the curve,ease of use leader,' Apple does not?
Can anyone help me to get OSX Tiger working for me at work?

I'm not sure what you mean by vague but allow me to be more specific.
To make Entourage work I had to configure it to use an Exchange Server, an option built in to the application. I find no such option in Apple Mail.
To make Firefox access the internet I just had to choose "auto-detect proxy servers." Now it will work at the office (through the Exchange server) and at home where I'm connected directly (on a cable modem). Safari has no such option.
I understand that Apple uses System Preferences rather than each application having its own settings. I ahven't been able to get any Apple apps to connect to the internet when I'm at work. I have set up a "Location" for when I'm at work. My MBP can access the company printers, though not from every application - - Preview always works.
I see that there is a place for a PAC file url or to configure a proxy server manually. I don't have this information. The company in all PC and isn't all that concerned with helping me configure my Mac.
If there's any other way someone can recommend I'd appreciate it.
On another note, I question why Apple's set up isn't easier. Entourage and Firefox were very simple, in the case of Firefox it was automatic.

ACE best practice for proxy servers

Dear,
I would like to know which is the best practice scenario to load balance proxy servers:
1- Best practice to have transparent proxy or proxy setting on the web browser?
2- for transparent proxy: best practice to use ip wccp or route-map pointing to the ACE VIP?
3- What are the advantages and disadvantages of transparent proxy V/S web browser proxy setting.
Regards,
Pierre

Hi,
Sorry, that seem to be an internal link.
You can also check the below post where a sample config is posted here for transparent cache.
https://supportforums.cisco.com/thread/129106
Best practice :
VIP would be a catch all address.
To optimize the caching predictor hash url is used.
You can also use mac-sticky on interface so proper flow persistence is used within ACE
The mode is transparent so we preserve the destination ip address.
Regards,
Siva

Application Server slowdown with multiple proxy servers ?

Our environment has our iAS boxes talking to iWS web servers which are front-ended with iPlanet Proxy servers (Proxy 3.53 I believe). We are seeing significant slowdown if we try and hit our web apps through the proxy as opposed to going directly to the web server (bypassing the proxy servers). One of our "proxy" guys recalls hearing that there is an issue with the app server's handling of sessions if requests from the same user come in to the web server (and by extension the app server) from multiple proxy servers with different ip's. Has any body ever encountered this or does any body know if the app server has an issue handling the same sessions whose requests come from different ip addresses (different proxies)?

The proxy work with HTTP 1.0 and the webserver with HTTP 1.1.
This difference could be the cause of your problems.

Creating java sockets behind proxy servers.

Hi,
I am trying to create a socket to an external server(i.e. a public server) from behind a proxy firewall, but the socket creation statement throws an IO exception. Can someone please let me know how to create sockets using proxy servers.
TIA
Shishir

I tried using java.net.Proxy for the connection. But the socket to the proxy itself is not getting created. It throws the IllegalArgumentException.
import java.io.*;
import java.net.*;
import java.net.Proxy.Type;
public class Client {
static Socket proxSocket = null;
static PrintWriter out = null;
static BufferedReader in = null;
public static void main(String[] args) throws IOException {
try {
System.out.println("Trying to create socket");
InetSocketAddress proxyadd = new InetSocketAddress(InetAddress.getByName("148.87.19.20"),80);
Proxy ps = new Proxy(Proxy.Type.HTTP,proxyadd);
Socket proxSocket = new Socket(ps);
out = new PrintWriter(proxSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(
proxSocket.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host: ...");
System.exit(1);
} catch (IOException e) {
System.err.println("Couldn't get I/O for "
+ "the connection to: ...");
System.exit(1);
catch(IllegalArgumentException e)
System.err.println("Unable to describe the proxy.");
System.exit(1);

PAC file support for Proxy Servers

When will AIR support PAC files for proxy servers?
In our network, we can't point to a PAC file because the AIR app simply ignores it, and we experience comms issues because of it. The workaround is to configure the network settings to point directly at the proxy, bypassing the PAC file.
This is a big problem as pointing directly at the proxy means a lot of manual configuration for each user that requires the use of the AIR app.
Any clues or suggestions?

Hi,
Additional configurations (DHCP and DNS) are required when you use Automatically detect settings.
For details, please refer to:

Cache FLV on Proxy servers?

Hi all,
We are planning to build a website that shows video through
Flash. The thing is that my customer does not want us to use a
streaming Server like Flash Media Server. (It's a shame)
Anyway, we are bound to use progressive download for Flash
Video files. I tried to find an answer on this, but so far no luck.
Maybe you can help me:
Do proxy servers cache Flash FLV files that are progressively
downloaded? I know the local client does, but the question is if a
proxy server can cache this too, so other people in a company can
view a video with minimum use of internet bandwidth that has been
downloaded before by someone else.
I hope you can help....

In the general sense of cache pollution (cache poisoning) - DNS responses contain additional records that do not pertain to the query in an effort to poison the DNS server's cache. No, there is no signature for this.
I know Microsoft has a "cache pollution protection" knob on their DNS servers and recent versions of BIND also contain code to perform some additional checks and ignore the non-relevant responses.

ACE to load balance proxy servers

Hi,
i have a set of 4 proxy servers that are already load balanced. But they are using a incorrectly configured health probe on the ace. I need to know a good configuration for a heath probe that will send a http request over port 80 , wait for response, and read it? I searched the forum and the cisco pages but could not find a proper answer.
the current probe is as follows:
probe http HTTPGET
description Tests that www.gmail.com returns 302 redirect
interval 10
request method get url http://www.gmail.com
expect status 302 302
-Gordon

Hi Gordon,
This is what you want to achieve :
I need to know a good configuration for a heath probe that will send a http request over port 80 , wait for response, and read it?
So ideally you have to choose what content you want to request and what you expect as response.
Any HTTP request will assume that the request is going to the web server or the device can understand HTTP and respond accordingly.
If you ask me I would say that the probes which you are using make sense.
If the probe fails that means the proxy is unable to reach "www.gmail.com" which is almost as good as proxy is not working.
Let me know your thought about it.
regards,
Ajay Kumar

Running windows 7 firefox refuses to come up, proxy server is refusing connections network adminiastrater says proxy servers are correct and is issue with firefox what do I do/ do

I start up firefox and it says the proxy server is refusing connection. It is configured to use a proxy server that is refusing connections. To check the proxy servers and ask network administrater to make sure proxy server is correct They say the proxy server is correct and it is a firefox problem. So what to I do now?

Make sure that the Firefox connection settings are the same as in IE.
You can find the connection settings in "Tools > Options > Advanced : Network : Connection"
If you do not need to use a proxy to connect to internet then select No Proxy
In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".
You can compare them with the IE settings in the Internet Options (Control Panel).
Control Panel > Internet Options > Connections: LAN Settings

Proxy servers and port 80

I don't know if this will transmit but I am suddenly losing contact with Apple discussions and get a white screen with a reference to Remote proxy servers / port80 / Apple discussions.
Would anyone know what is going on and if the problem is my end or Apple's.
Much obliged for some info.

Actually you're right they are working on it but if we talked about the fix here we'd have to kill everyone below level 6.

Any suggestions for optimal configuration of cache on mulitple, high volume proxy servers?

I am trying to optimize the cache on 12 proxy servers running Sun ONE Proxy 3.6 on Solaris 8. They are not set in an array at this time. Forward proxying only. I have 3- 36G drives available per box for cache. Traffic volume - approximately 50,000 users.

Hi James,
          The typical configuration is to only use LocalDirector to balance the load
          across the web servers. Since the web servers are using our plugins to
          route the requests to the cluster based on information encoded in the
          session id, you do not need to (and should not try to) use Local Director
          between the web servers and the app servers.
          Hope this helps,

Proxy Servers, Password Resets/Expirations and Password Policies

Our current configuration has two directory proxy servers and two directory servers, all running DSEE 6.3.1. The LDAP clients point to the proxy servers and the proxy servers point to the directory servers.
When the LDAP clients user the proxy servers, users aren't notified on password resets or expirations. When I point one of the LDAP clients directly at on the directory servers, bypassing the proxy servers, the expected behavior of being required to change a password on reset or notification of password expiration works fine.
We would like this to work via the proxy servers as well. Can anyone point me in a direction or two to determine why this isn't working as expected ?
TIA!

I opened a service call on this and in speaking with the rep, who was reading the CR mentioned in the first reply, he said it contained a note about the fix being scheduled for release in DSEE 7.x. I'm not sure if it made it into the recently released 7.0 or not.
A patch released for the 6.3.1 proxy servers on the 21st of December didn't include mention of the CR in the notes, although there was mention of another CR that sounded like it might be related.
Since it appears the CR was created in late November, I'd be surprised if either the DPS 6.3.1 patch or the 7.0 full release address the CR. In either case, I'm assuming you'll have to wait if you don't have a support contract with Sun that covers DSEE.

Visits through proxy servers (was: Just plain CREEPY!)

Has anyone else had this happen to them. I have inserted CODE on all my websites to TRACK anyone visiting my websites pages…
Since I joined the Adobe forum ALL the visits that are germane to this forum are 90% through Proxy servers!!!!!!
But that's not even the creepiest part… Why am I getting visited from the following IPs since joining the adobe Forums…..
The US Department of Justice
The US Secretary of State
The US Department of the Army
The Colorado State Secretary office and
and of all places... NASA!
And countless PROXY servers!

I have just returned from a meeting in which we discussed your case.
In trying to get to the bottom of the situation, we even considered if the 13th April may have been a factor. We soon realised that this could not be the case because when I first heard of it in the morning of 13th April, half the world would still register 12th April as the date.
