HTTP pipelining support in WL Server

Greetings,
I've just noticed that the "HTTP pipelining" support in Mozilla-based browsers
appears to break WL 5.1.0 web apps when enabled. The symptoms are pages that
take forever to load, with images misplaced throughout the content (i.e., icons
will ne exchanged in what appears to be a random manner).
I posted a bug with the Mozilla team, and it looks like connections are being
recreated and torn-down repeatedly, as if each request is being cancelled.
Since the HTTP/1.1 spec requires that servers support HTTP pipelined requests
from clients, Mozilla/Netscape has no choice but to add the WL server string to
the "pipeline blacklist".
The workaround is easy: disable HTTP pipelining. I'm just wondering if WL 6.x
or up meets the HTTP/1.1 spec in a more standard manner (at least in this regard).
Is this a problem for other apps out there? On other versions of WL?
Full pipelining support would be nice, as it significantly speeds up requests,
with a lot more information squeezed into every HTTP request. We are finding
that our web-based apps are becoming ever more popular; which means an ever-growing
number of customers requesting we make them more responsive.
HTTP pipelining is not a magic bullet, or an excuse to make poor web-based apps,
but it really helps at the connection layer to make each request more efficient.

  • Network.http.max-persistent-connections-per-server keeps reverting to user set 4

    I didn't used to have this problem as far as I'm aware, but as of recently, I've noticed that if I try to download more than 4 of one thing at a time from the same site, it would fail. For instance, if I have up 5 web pages of streaming content, only 4 will load, the other 5th one will do nothing until I finish one of the others. Upon looking up some information on this, I saw that the network.http.max-persistent-connections-per-server is set at "user set = 4", and if I change that number to anything else, it corresponds. If I click to 'reset' the number, it goes to the default of 6 - which is still less than what it used to be. I used to not even have a limit on this as far as I'm aware, or if I did, it was well beyond 10 and that wasn't a product of me manipulating it.
    What I'm asking is this:
    1) How do I make this so it permanently switches to a higher number? Every time I reset it to 6 or I manually change the number to something higher, once I close it, those settings go back to 4.
    2) Why is it reverting and not staying the way I change it?
    3) What's the purpose of this and why is it just recently doing it when I haven't put any new add-ons or made any other refinements to Firefox that I'm aware of?
    Any help would be appreciated

    Two possible causes for it resetting to 4 that I can think of.
    # You have an add-on handing that pref and that is resetting it to 4 when Firefox is restarted.
    # That pref is set via user.js and that causes it to go to that value as Firefox starts.

  • The server responded with "HTTP/1.1 500 Internal Server Error" to operation CalDAVAccountRefreshQueueableOperation

    My iCal is no longer syncing to Mobile Me. This is the error that pops up:
    The server responded with
    “HTTP/1.1 500 Internal Server Error”
    to operation CalDAVAccountRefreshQueueableOperation

    Erik,
    Where you able to find a solution to this error? I have been combing the internet (and these Apple Support pages) but I cannot find any way to resolve this. Now, suddenly one calendar from MobileMe shows no events in iCal, although the calendar itself is there. I am having the same results on two separate laptops, one is a G4 running Leopard, and this MacBook (Intel) running Snow Leopard.
    Hope you got it back up and running. I'd love to hear how.
    Cheers,

    Hi,
    In addition, I recommend you check whether you have additional Authentication methods (like ASP.NET Impersonation) enabled. 
    Disable the authentication method and try again.
    Also, please review the link below, here is a article about troubleshoot ISAPI filter issue.

  • Librfc32 support on Windows server 2008

    Hi,
    We at Trango Software (division of Siemens Enterprise Networks) are currently using the SAP Remote Function Call runtime as a part of our product (librfc32.dll, File Version 6403.3.55.4580). We will be supporting Windows Server 2008 platform from our product's next release. We are assessing compatibility on Windows Server 2008 platform of all the third-party libraries and tools that are part of our product.
    We would like to know if the SAP remote function call runtime dll (librfc32.dll) is currently supported with Windows Server 2008. If not, we would like to know when (tentatively) it is expected to be supported.
    Thanks a lot for your help.

    Hello,
    have you configured the accounts to have the permission "Log on as a service"? I have seen that this is not given to the account and therefore the service fails to start.

  • Microsoft support for Windows Server 2008 R2 on vSphere 5.5

    Hi, everybody.
    I'm checking if Microsoft will provide support for Windows Server 2008 R2 running on a VM on vSphere 5.5 Update 2. So far what I've found at
    http://windowsservercatalog.com is:
    Filtering vendor VMware and Windows Server 2008 R2, it shows vSphere up to version 5.0 update 1
    http://www.windowsservercatalog.com/results.aspx?&chtext=&cstext=&csttext=&chbtext=&bCatID=1521&cpID=2274&avc=34&ava=0&avq=0&OR=1&PGS=25&ready=0
    http://www.windowsservercatalog.com/item.aspx?idItem=c92e5cbd-9690-b62a-2ace-843390ac3ea4&bCatID=1521
    Filtering vendor VMware it shows vSphere 5.5 update 2, but details only Windows Server 2012, not Windows Server 2008 R2.
    http://www.windowsservercatalog.com/results.aspx?&chtext=&cstext=&csttext=&chbtext=&bCatID=1521&cpID=2274&avc=0&ava=0&avq=0&OR=1&PGS=25&ready=0&PG=2

    Does that mean Microsoft doesn't support Windows 2008 R2 on vSphere 5.5 update 2?
    I'm aware Windows Server 2008 R2 lifecycle is close to EOL, but customer requires this specific version for application compatibility.

  • Alias support in directory server 5

    Hi,
    Is alias dereferencing supported in Directory Server 5? (It is
    mentioned in this article that 4.1 did not support it:
    http://java.sun.com/products/jndi/tutorial/ldap/misc/aliases.html).
    I am trying to do a search using an alias and it does not seem to be
    working. I keep getting the alias entry rather than the referred
    entry. I tried setting the DEREF option to DEREF_ALWAYS but this does
    not seem to help (code fragment below). Do I need to do something to
    enable alias dereferencing on the server? Could it be the version of
    LDAP SDK for Java that I am using?
    LDAPConnection conn = new LDAPConnection();
    conn.connect( "XX.XX.XX.XX", 389 );
    conn.setOption( LDAPv2.DEREF, new Integer( LDAPv2.DEREF_ALWAYS )
    LDAPSearchResults results;
    String filter = "(cn=adminalias)";
    try {
    results = conn.search( "o=aliases,c=com",
    LDAPConnection.SCOPE_ONE, filter, null, false );
    while( results.hasMoreElements() )
    System.out.println( results.next() );

  • HTTP Digest Authentication in Weblogic Server ?

  • Recommended and supported Hyper-v Server configurations

    I am looking for a document that will give me some suggested Hyper-v supported and recommended server configuration. Recently our company rolled out two Hyper-V servers. The host system is configured to be the Domain Controller. 
    One server was configured to be a Host Server Domain Controller and a virtual server Exchange server.  The Exchange server failed three times.  The host domain Controller had been put into services and was active.  I finally called Microsoft
    and was told this would not a supported or recommended configuration and it would continue to fail.  The technical help I had was very good and he pointed me in the right direction to building it directly on the domain controller.  Since the Exchange
    server had already been built and the scheme to the domain controller had been extended this was horrendous but it worked.  "Thank you Microsoft technical team."
    The second Hyper-V server is setup the same the host server is the DC.  The current virtual server is a SQL server.  This seems to be working. We had some issues at first with network connections but I made some DNS entries and it seems to be stable
    now.  This system is to have an Exchange host added to it and I'm worried that it will have the same issues as the first server.  I would like to add it directly to the DC as I finally did the first time but I'm worried it will make the SQL server
    fail. 
    This is currently in a production environment?  Does anyone have any suggestion or can you point me to a good tech document that discusses configurations?
    Thank you.
    Bonnie Whalon

    Hi Sir,
    >>I would like to add it directly to the DC as I finally did the first time but I'm worried it will make the SQL server fail. 
    As far as I know , install exchagne on a DC is not recommended (I know it should work).
    As to hyper-v serve , it is still not recommended to enable other role on hyper-v host .
    I would suggest you to create two VMs , one is DC , other one works as exchange server (If it is possible please build another DC VM for redundant and backup them regularly ) .
    Virtualize exchange please refer to following article :
