Any idea why dns-related .pac functions only half-implemented?

My first post! How exciting...
I work for a fairly large company which requires proxy access to get to external (internet) sites. But, due to the number of clients we have (and due to the fact that it just kinda seems silly), we don't want clients going to the proxies for internal sites.
Due to the fact that we have a ton of machines both inside and outside of our proxies/firewalls and that many use the same domain name, we rely heavily on functions such as dnsResolve, isResolvable, and isInNet to determine via a PAC file whether or not to go to a proxy or not. After all, even though I have a bunch of box names with the same domain suffix (making hard-coding of DNS names in the PAC file a ludicrous idea), we currently only have a handful of network IP address segments on the internet. This way, we can say using isInNet "if host is on IP address segment x.y.z.0/255.255.255.0 then go to proxy, else stay direct."
This works great for the several thousand browsers we have deployed. Unfortunately, now that we are looking to upgrade from the MS JVM/JRE to the Sun JVM/JRE , we see big problems with these functions as they only work with IP addresses.
Really. The whole point of DNS is to resolve DNS names to IP addresses. So the fact that a function named dnsResolve would not perform a forward lookup eludes me.
According to the documentation, these functions only work on IP addresses. Does anyone know why the forward functionality was left out?
Thanks!

Sorry, guess I wasn't too terribly clear.
Java 1.4 supports .pac files for proxy autoconfiguration. From what I have read, java uses the javascript engine supplied by the browser, but the runtime internally defines the functions required for using a .pac file. These include shExpMatch, dnsDomainIs, and others. These are not java functions that can be used in applets or applications.

    The problem of tracks becoming de-linked between iTunes and the music files in your iTunes music folder happens for different reasons - this seems to come up fairly commonly in this forum.
    The solution can be to locate each song in the iTunes library, as you mentioned - or, but wait, before I get to that...
    trouble finding the original track in your iTunes music folder? maybe look for it under compilations, or if not using the 'group compilations preference' then look in the folder under the songs artist name, but what song artist name iTunes uses depends on what you have in the metedata tag spot for album artist or song artist. Any varyation in artist name spelling, in the menu item 'get info' metadata for any selected individual track will cause iTunes to create that as a separate artist folder in the library, even names like 'various' or any difference at all (even the word 'the' can change where in your iTunes music folder a track gets placed by iTunes). You can try to use the finder function of find file (finder munu item outside of iTunes) to locate hard to find items.
    Back to how to re-link any de-linked tracks .
    There may be scripts that can help re-link de-linked music files - or, at least provide you a list of such files, Scripts are easy to install and use...
    at Dougs Scripts, there is one called iTunes Track CPR that might work
    http://dougscripts.com/itunes/scripts/ss.php?sp=itunestrackcpr
    or, if you just want a list of de-linked tracks, go to
    http://dougscripts.com/itunes/
    and find the script called List MIA's, this will create a text file listing all de-linked tracks

    Hello! It is my understanding that you need to add the individual files to the Source Code Control along with the .lvproj file.

  • HT3275 I've 1.85TB empty space on my time Machine, but it only backs up to the beginning of the previous month. it should have weekly back-ups for every month before that. Any ideas why it deletes stuff older than a month?

    I've 1.85TB empty space on my Time Machine, but it only retains back-ups to the beginning of the previous month. I should be able to access weekly back-ups for every month before that until the disk is full. Any ideas why it deletes stuff older than a month?
    Thanks, Rigby.

    If you are using Ethernet to connect your Mac to the Time Capsule, are you allowing at least 2-3 minutes for Time Machine to fully load when you open the application to see your backups?
    If you are using wireless to connect, you may need to allow 8-10 minutes or longer for everything to fully load, depending on the speed of your wireless connection.
    If you see only white time "bars" on the timeline at the right of the screen, you are seeing temporary backups. Permanent backups are displayed with purple "bars".

  • Any idea why itunes is only downloading part of each song I purchase?

    Any idea why itunes is only downloading part of each song I purchase?

    Not really, a bug I suspect...
    Assuming you are in a region where you are allowed to redownload your past music purchases, delete the corrupt tracks from the music section of your iTunes library, close & then reopen iTunes, go to the iTunes Store home page, click the Purchased link from the Quick Links section in the right-hand column, then select Music and Not on this computer. You should find download links for your tracks there.
    While downloading select Downloads in the left-hand column and make sure Allow Simultaneous Downloads is unchecked. This seems to help with partial downloads...
    If the problem persists, or that facility is not yet available in your region, contact the iTunes Store support staff through the "Report a problem" links in your account history, or via Contact Support.

    How to Remove “Other” Data from iPhone, iPad and iPod Touch
    http://www.igeeksblog.com/how-to-remove-other-data-from-iphone/
    With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

    I'm from germany so no 'best buy' but I think I will lock around sleeve/bag for a different product with same measures. Any tip?
    The clear plastic case is not what I want. I would like to use the player without such protections. I just want a sleeve to protect the player while its in my jacket/pants.
    Btw, i have bought this version: Creative Zen (maybe european version?). I also doesn't seem to have your mentioned sleeve. I also couldn't find it on the website.
    Anyway, thank you,

  • Changes that i make to song display in iTunes, will not carry over when I sync to my ipad. This is only since i upgraded to ios7 and downloaded the latest itunes. Any ideas why?

    I use my iPad for music when i teach my dance class. The default layout in the music program on iPad is: song title, artist and album. I need the name of the dance, so in iTunes, I right click on the song title, then choose "get Info".  I then edit the info and under album title I write in the dance name. Then when i sync the iPad still has the same three columns, but the info i need displays under the album column.  UNTIL i upgraded to ios7 and installed the latest iTunes.  When I synced last night, after adding new music, the songs that were already in the playlist, stayed the same. ALL the new songs were placed in the playlist but none of the info that i edited synced.  It shows it as i want it when i look at the playlist in iTunes, but it does not carry over after the sync. 
    I hope this makes sense and does anyone have any idea why?

    Amazing! I'm a dance instructor and am doing the exact same thing as you - and not seeing what I need on my iPad Air ... I can't believe there has been no reply on this! I also can't believe there isn't an easy way of seeing track info in the iPad or iPhone but I've spent hours searching and am not finding anything

    Me: Yes
    Adobe: It means, issue is with Graphic Card drivers.
    Me: Yes, I knew that
    Adobe: I suggest you to contact Graphic Card drivers and check if you can re-install the drivers and use Photoshop CC 2014 with the Graphic Card
    Me: SO... PS CC 2014 is incompatible with the AMD drivers?
    Me: I've installed 4 versions already. I'm running the latest beta now
    Adobe: Could you please provide me with Full name of the Graphic Card?
    Me: AFAIK, PS CC2014 is the only program that causes this error
    Me: AMD Radeon HD 6700
    Adobe: Dan, issue is due to the Drivers, which are not compatible with Photoshop CC 2014.
    Adobe: You may be able to use other products, however if drivers is not compatible with Photoshop CC 2014, you will not be able to use them with Photoshop CC 2014
    Me: I think that you have that backwards. PS CC2014 is not compatible with the drivers. It is the only known program to have this problem. Well documented.
    Adobe: Please contact Graphic Card provider and check for the drivers or re-install drivers and check.
    Me: I did, and they blame Adobe
    Adobe: Okay
    Adobe: Photoshop CC 2014 is not compatible with the drivers you have for the Graphic Card, there might be issue with drivers.
    Adobe: We have checked with the error logs as well., it show  Fault Module Name: atiocl64.dll 
    Me: Again, PS CC 2014 is the only known program to clash with atiocl64.dll
    Adobe: I can suggest you to check if you can use the product from new Account and use the product or check with Graphic Card provider for the drivers or a proper installation for Graphic Drivers.
    Me: Again, I've done all of that
    Me: They blame Adobe, and frankly, they are correct. The problem only happens with your product
    Adobe: Please use different Graphic Card on your computer and check if you can use it with Photoshop CC 2014.

    Me: Yes.
    Me: So PS CC 2014 will not work with this card?
    Adobe: Issue is with Graphic Card drivers, we can use Product with graphic Card
    Me: So PS CC 2014 will not work with this card?
    Adobe: Photoshop CC 2014 is compatible with AMD/ATI Radeon, 6000 series.

  • My mac OSX lion is now very slow, any idea why?

    my mac OSX lion is now very slow, any idea why?

    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with a visit to: OS X Maintenance - MacAttorney.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion/Mountain Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Data Backup
      3. Deja Vu
      4. SuperDuper!
      5. SyncTwoFolders
      6. Synk Pro
      7. Synk Standard
      8. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
