Ical, caldav and Web proxy.

Hi,
I have configured ical with an external caldav server. The caldav URL server is reachable using http or https. The synchronization works fine at Home where I don't use web proxy to access to Internet. But at work, even if the network is properly configured with the proxy (Safari is working fine with the proxy configuration), ical seems to not be able to use the web proxy. Then, the synchronization is not working at work.
Is there any limitation for ical/caldav to work through web proxy?
Thanks.
LauDai.

I have exactly the same problem. A network expert suggested that the problem could be in the proxy. The CalDAV protocol used by iCal is an extension to the standard HTTP protocol, and apparently not all proxies can deal with the extensions. I don't know if there is a way to check if this is the cause of the problem.

  • Ical print and web formatting

    i am using ical to present a monthly schedule to my department. i have color coded the events by creating different calendars and made them 'all day events'. when i try to print it -- the order of the events get shuffled around with no apparent ryhme or reason...i thought it maybe the order in which i entered the envents, but no. if i drag the all day event that i woudl like to appear first on the day...it looks right on my screen...then when i print it is flipped. i am frustrated and about to give up and create my own calendar in excel...which i really do not want to do....beacuse i would also like to share this calendar by publishing it with my mac account....in a seperate issue...when i publish it online -- the color coding is removed....is there any way to fix this???

  • Safari 3.x (Leopard) and Web Proxy Server Problems:

    I have a Squid proxy server running on Linux. Users web traffic is directed through it via WPAD server which hosts a simple PAC file. The PAC files is very clean and small. It basically points all external (Internet) web traffic to our Proxy server. All of our Windows, Linux and Tiger clients work fine. However, Leopard (Safari 3.x) doesn't work quite right. Here's what happens:
    Mac user logs into a Leopard 10.5 Mac. User launches Safari and tries to go to an external (Internet) site. The WPAD server is contacted and the Mac User is prompted to authenticate to the Proxy server. This is totally normal behavior thus far. Then, however, every few minutes the Leopard Mac user will be prompted to authenticate again (sometimes 2 or 3 times in a row!). Firefox 2.0.x, when configured to use the WPAD/PAC server and Proxy server, works fine in Leopard. Only Safari 3 in Leopard is having the problem.
    All the Macs (Tiger and Leopard) are configured to use the Proxy server via OS X's Network Pref Pane (using the "Automatic Proxy Configuaration"). Reminder: Tiger works fine (even with the Safari betas), but Leopard's doesnt not.
    I have attached our PAC file inline below (some things edited for privacy):
    // SIMR automatic configuration for Mozilla and friends
    // $Id: wpad.dat,v 1.8 2005/12/14 20:18:23 dct Exp $
    // Edit carefully, since many may be relying on this...
    function FindProxyForURL(url, host) {
    // Bypass the proxy for internal addresses
    if (!url.match("http:")
    || url.match("http://127.0.")
    || url.match("http://10.")
    || url.match("http://192.168.")
    || isPlainHostName(host)
    return "DIRECT";
    // These are exceptions given in the IE config for Windows.
    if (host == "www.ncbi.nlm.nih.gov"
    || host == "chabry.caltech.edu"
    || host == "flybase.bio.indiana.edu"
    || host == "www.fedex.com"
    || host == "domain.org"
    return "DIRECT";
    return "PROXY <proxy server>:8080";
    }

    I think I have a similar problem. I am a Mac connecting to an otherwise all PC school network.
    A new location with all correct proxies has been set up. However, Safari always crashes on first attempt to negotiate its way through our server to the internet. Internet explorer gets through because in its preferences it is possible to include the name of the school domain as well as my user name and password.
    We have been unable to find any way of including the domain name into Location in Network or into Safari.
    However, once Internet Explorer has negotiated with the server I can launch Safari and it works as normal.
    Safari/Network seems to lack this option of including a domain name that my PC server requires.
    Make sense to anyone?
    Worth mentioning that my copy of Internet Explorer (5.2) often crashes, but usually it has done its job by then. I quite like the concept of Internet Explorer sacrificing itself to clear a path for Safari.

  • ICal, sharing, and web stuff - hoping for some clarity.

    Hi,
    apologies if I ask already answered questions, but I am getting somewhat confused. Here si my situation.
    New photography business. My wife uses a MacPro tower, I use a MacBook Pro, and we have a spare Powerbook sitting doing nothing.
    1. We want to access and edit the same iCal calendar.
    2. We want to be able to put it online - but not critical as yet.
    3. We want to sync 2 iPhones.
    So, if money were not the issue, what is the ideal solution? Is it putting Leopard Server on one of the machines? (would the old PowerBook do the job in the background?)
    Is CalDAV the way to go, something I know absolutely nothing about? I suppose I am so confused about which direction to head in I am hoping someone will point me.
    I will happily get Server if that is better, but is it?
    Looking forward to an enlightening reply.

  • Acrobat and Web Proxy Servers

    Hi
    I'm not sure if this is a Livecycle question or an Acrobat Question.
    We have a Livecycle form that calls a WebService - this works fine on the internet.
    One of our customers has a Proxy server, which does a redirect to force their users to enter a Username + Password.  Acrobat generates a "Network error" in this environment
    Is there anyway Acrobat can mirror this for the WebService call?
    My expectation is no - and that the url for the WebService needs to be added to a Proxy whitelist or similar
    Thanks,

    You are correct ....Acrobat will not know what to do with the authentication prompt from the proxy.

  • Lync 2013 Edge & Web proxy

    Hi Everyone
    I'm having a little trouble getting my head around the setup for Lync external access.
    I have setup an ADFS server, Lync 2013 server(works internally), 2012 web proxy server(doing nothing) and an edge server(currently doing nothing).
    My understanding is that the Edge and Web proxy server are in "parallel", I.E, they both face the WAN as they perform different tasks.
    The problem I have is that I'm unsure how to map everything correctly, I also don't understand how an external Lync client will get it's config. If my domain setup is:
    something.domain.internal, and I would like to register a DNS entry externally as something.domain.external. How do I map those correctly via the web proxy and edge server? Sending the request via the firewall is easy enough, however I'm unsure how I'm supposed
    to define them on my servers. Is the Lync server supposed to know about the external URL? Or does it not care?

    Hi,
    The Edge Servers run the services that allow external access to IM and presence, conferencing, audio/video, and other media services. You can also configure the Edge Server to federate with other Lync Server and other XMPP deployments.
    Lync Server uses the reverse proxy to publish a number of features, such as conferencing meetings, conference join locations, the address book, distribution list expansion, downloading meeting content, device updates, Mobility services, and more. Any reverse
    proxy that can meet the requirements for publishing the necessary resource locations can be used.
    You just need to define the Edge information in topology builder and publish it. Then configure the server as defined in topology and install local configuration store, setup Lync components and assign certificate. Here is a topology that
    using private IP addresses and NAT.

  • Help - cannot access web service outside web proxy

    I'm trying to access a public web service - and web proxy stops me from doing it.
    Here is my code:
    package test;
    import java.rmi.RemoteException;
    import javax.xml.rpc.ServiceException;
    import net.webservicex.www.WeatherForecastLocator;
    import net.webservicex.www.WeatherForecastSoap;
    import net.webservicex.www.WeatherForecastSoapStub;
    import net.webservicex.www.WeatherForecasts;
    import java.net.*;
    import java.io.*;
    public class TestOutput {
    public static void main(String[] args) {
      initialiseConfiguration();
      printForecast();
    public static void initialiseConfiguration() {
      System.setProperty("http.proxySet", "true");
      System.setProperty("http.proxyHost", "proxyserver");
      System.setProperty("http.proxyPort", "8080");
      System.setProperty("http.proxyUser", "userid");
      System.setProperty("http.proxyPassword", "password");
    public static void printForecast() {
      try {
       WeatherForecastLocator wfl = new WeatherForecastLocator();
       WeatherForecastSoap wfs = wfl.getWeatherForecastSoap();
       WeatherForecasts forecasts = wfs.GetWeatherByZipCode("90210");
      } catch (Exception e) {
       e.printStackTrace();
    }Here, I was using the test web service located in www.webservicex.net/WeatherForecast.asmx
    I've created stubs using Eclipse (package net.webservicex.www) in another project, compiled into a jar, and imported into the test project.
    The test is working beautifully from my home. It's failing in the office with the error:
    AxisFault
    faultCode: {http://xml.apache.org/axis/}HTTP
    faultSubcode:
    faultString: (407)Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )
    faultActor:
    faultNode:
    faultDetail:
    {}:return code: 407
    It's failing when it's trying to execute
    WeatherForecasts forecasts = wfs.GetWeatherByZipCode("90210");
    The "initialiseConfiguration" function is doing its job OK - it's actually helping me to go through the proxy - if I'm doing simple stuff like accessing internet sites. I've tested it - I can get to any external site and read from it. The moment I disable "initialiseConfiguration", I can't get through the proxy.
    So, probably, the problem lies in the web services client classes generated by Eclipse and based on axis. Maybe, the code gets through the proxy, but then starts to do something without authentication??? (I'm not sure if it's possible at all, but who knows...)
    I've read a lot of postings on this subject and couldn't find a solution that would work for me. I'm very surprised, because my situation is very common - there are more and more public web services, and most organisations have firewalls. Obviously, I'm making some very elementary mistake.
    Please help

    We have the same problem, not with SOAP but with XML-RPC (err 407). We're still stumped, and i agree that the problem should be common, but i don't see the mistake, so it's not that obvious.
    Hypothesis: the proxy is spying on the requests content , and filtering out xml. Can you check that ?

  • Does Sun ONE Web Proxy Server have built-in log analysis tools? What kind o

    Sun ONE Web Proxy Server automatically logs all requests using either the common log-file format or an extended log-file format. The extended log-file format includes the referrer field and user agent. You can also create your own log file format by selecting which HTTP fields you would like to log. A built-in log analysis program includes reports such as total number of requests, total bytes transfered, most commmon URLs requested, most common IP addresses making requests, performance during peak periods, cache hit rates, and estimated response time reduction. The items logged and the analysis program are completely configurable using the server manager's HTML form.

    Sun Java System Web Server is a web server; it serves web pages to web clients. Sun Java System Web Proxy Server, on the other hand, is a web proxy server; it routes requests/responses between web servers and web clients.
    You can configure Web Server to act as a simple reverse proxy by installing the Web Server 6.1 Reverse Proxy Plugin. This doesn't provide any of the forward proxy or caching proxy functionality found in Web Proxy Server.
    Both Web Server 6.1 and Web Proxy Server 4.0 are supported on Solaris 10.

    Hi Naseer,
    This is a very generic error.
    You need to provide us more information on the error.
    Alternatively, speak to your DBAs and see the external site is working fine.
    Did you add the External visitor responsibility to the GUEST user ?

  • Dynamic Host and Port for Web Proxy

    hi,
    When I create a web proxy in JDev I supply the hostname and the port for the web service. The code is then compiled and then deployed. However I want the host and port to be dynamic (kept in a varaible) so when I move my deployment from Development to Test server I just need to change a value in a database or text file. I don't want to re-compile and deploy the code when I move servers. Is there any way to do this??
    Thanks

  • IPlanet Web Proxy Server 3.6 and emptying out the cache.

    Hello.
    I'm wanting to empty out our proxy server's cache in an attempt to resolve one of our users help desk problems - a web site they are accessing is not loading correctly when going through the proxy server, bypassing the proxy server works.
    The problem is that the technician who implemented our iPlanet Web Proxy Server 3.6 has left the company and no one else is aware of how to do this. Can anyone advise of what has to be done to achieve it? Thank you.
    Kind regards,
    Jimmey.

    Hi
    This as per the HTTP/1.1 RFC (RFC2616)
    The Connection general-header field allows the sender to specify options that are desired for that particular connection and MUST NOT be communicated by proxies over further connections.
    The Connection header has the following grammar:
    Connection = "Connection" ":" 1#(connection-token)
    connection-token = token
    HTTP/1.1 proxies MUST parse the Connection header field before a message is forwarded and, for each connection-token in this field, remove any header field(s) from the message with the same name as the connection-token. Connection options are signaled by the presence of a connection-token in the Connection header field, not by any corresponding additional header field(s), since the additional header field may not be sent if there are no parameters associated with that connection option.
    Read the following at
    http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.3
    and
    http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.10

  • My Wikis and Ical on the WEB  give a Server starting up.. message

    Wikis (and Ical on the WEB) give a Server starting up... message with the turning wheel. They were working perfect, and yesterday started the problem. I have not changed any of the server settings neither permissions. From Mozilla Firefox on windows throes an Mac OS X server message
    500: An internal error occurred trying to process your request. Sorry. Safari gives a Server starting up..
    I checked permissions and look ok, root and admin group have read & write access. to
    /Volumes/DATA HD/ServiceData/Web/Documents/Collaboration folder and up in the path.
    Does anybody know how to solve this?
    I tried updating to OS X 10.6.5 but the problem continues.

    I am having a similar issue as you marktech, with colaboration folder on a different drive.
    My temporary solution is to stop and start web services on the server, and the message goes away and users can log in.  Problem comes back on a server restart.
    Swamped here so have not been able to apply troubleshooting techniques.
    What I have checked is verifying permissions on collaboration folder.  Seems like I had to re-apply permissions after any significant update.
    My final resolution will be to migrate from the ssd hard drive (the extra speed is not any significant impact for us) to a 1TB hard drive and migrate data back over to a single drive in original directory locations.  appologies have not had ample time to research the issues....

  • BB Link and McAfee Web Proxy

    I'm having an issue getting any BB10 device to connect to BB Link.
    I've managed to figure out the issue is related to McAfee Web Proxy that we use, since if I uninstall the software or allow it to be disabled for a period of time, I can connect the device without any issues.
    While I know the BB Link software has no options for proxy settings, I'm hoping someone would be able to help me figure out what sites the software tries connecting to, so I can bypass them and resolve my issue.
    Already tried talking to McAfee, but they won't help me as apparently they don't support smartphones/tablets, even though their software isn't running on any of those, but the Win7 computer with BB Link.
    Thanks!

    Hi ApolloX2,
    First of all, a few thoughts about the problem you're facing here
    1. Actually deciding if the server is not available is not an easy task: a server can be slow to process a request and send the answer but still be available. On the other hand, the server can answer, but return an error (anything from "410 Gone" to "500 Internal Server Error" to redirects). Did you consider all these cases?
    2. Detecting when/if all the resources on a page have been loaded is another hard to solve problem: there's no event on the HTMLLoader to signal when *all* content was successfully loaded, and the matter is even more complicated when you consider dynamically generated/loaded content via JavaScript/AJAX.
    Of course, things can be simplyfied if you don't want to load "free-form" (arbitrary) web content but rather your application will load only content with a previously known structure/in a previously known setting. Either way, you'll still have to manually identify the resources you want to save and save them.
    If you have some prior info about what you're going to display (and save), you could parse the HTML loaded inside the HTMLLoader. The HTMLLoader object exposes the DOM nodes as dynamic properties. You can take a look at how that's done inside the AIRIntrospector framework that's shipped with the AIR SDK. You can find the source in SDK_PATH/frameworks/libs/air/AIRIntrospector.js .
    Hope this helps,
    Mihai

  • Validating XML offline: is a web-proxy and cache the solution?

    Is implementing a web-proxy and cache, the solution to offline XML validation?
    Our application uses XML to store data (local, and remote: it's up to user), but needs to work even when offline. This is a problem for the validated XML, since it's DTD may be located on a remote server. To complicate things, we would like to allow others to extend our application with data-formats (DTD's) of their own.
    At the moment, the DTD is stored in the applications jar file, but this is going to be a problem. In the data files, the URL for it's DTD includes the jar file's system dependant path name. If data files are moved to a different system (where paths are different) this will no longer work. As you can guess, simply using relative URL's (using the data file or the even the Application jar as Base URL) will also cause problems.
    Before concerning ourselves with offline editing, we ran into the problem of firewalls. This we could circumvent by setting Java's global HTTP proxy (thanks to http://www.javaworld.com/javaworld/javatips/jw-javatip42.html for the tip)
      if (userNeedsProxy) {
        System.getProperties().put ("proxySet", "true");
        System.getProperties().put ("proxyHost", userProxyHost);
        System.getProperties().put ("proxyPort", userProxyPort);
      }Which appears to affect all URL.getStream() calls for http URL's, so works fine.
    To get around the offline problem, I'm thinking of implementing my application as a 'proxy', and caching any downloaded DTDs locally. This cache could be seeded with our apps default DTD, and any extensions can take advantage of this as well. This solution has the benifit of not modifying the basic XML parsing routines or doing something undesirable, like just turning off validation (suggested on other forum threads). Would this involve creating a custom URLConnection object and or URLStreamHandler?
    Any suggestions or comments are welcome, as I haven't started this, and I'm pretty sure it has been solved before. Does this sound feasable, or insane? :) Any experience shared is very appriciated!
    Thanks in advance
