“Content-Encoding: gzip” is stripped by proxy?

When you send an HTTP request through a proxy, and the web site returns an HTTP header like this:

HTTP/1.1 200 OK

Content-Encoding: gzip

There is a chance that line “Content-Encoding: gzip” could be stripped by the proxy.  Here is some research I did if the proxy server is Microsoft ISA Server 2006.

1) There is an article in the official blog: http://blogs.technet.com/b/isablog/archive/2009/10/25/error-500-not-supported-while-browsing-internet-through-isa-server-2006.aspx

How do I reboot, power cycle ProLiant server in iLO?

The options to restart a server using the iLO are contained under the virtual power tab. You can do one of four options:

  1. Momentary press – this is like pressing the power button on your laptop/pc or server, with Windows 2000 and above (if I remember correctly), it should cleanly shut down the operating system.
  2. Press and hold – this is like pressing and holding the power button, it will turn off the computer completely and will not cleanly shut down the server.
  3. Cold boot of the system – this effectively powers off the server and restarts it.
  4. Reset system – this is the iLO way of rebooting it without cleanly restarting the operating system, if your server has hung and won’t respond, this might be the option you select.

iLO “Remote Console is unavailable. It is already in use by a different client”

When you try to access the iLO Remote Console on some servers you sometimes get the message “Remote Console is unavailable. It is already in use by a different client”. But there is no other client connected to the iLO on that server. How can you “reset” the Remote Console connection (from remote) to access the server through the iLO again?

Solve the problen by simply going to “Administration -> Settings -> Network -> Apply” (no changes to settings and just applying the current configuration)

It disconnects all connections, you may able to connect the remote console now.

Another solution:

When using the integrated remote console on a HP Blade Server and you get disconnected for whatever reason you get the error message “The Integrated Remote Console is unavailable; it is already in use by a different client.”.

This is a common problem and is apparently working as intended, though it can be annoying. To fix this you need to turn on “Remote console acquire” within the iLO of the system.

Log into iLO and select Remote Console / Settings
There you will see settings that allow you to enable:
– Remote Console Acquire
Acquire allows you to terminate the current remote console session to attach a new one. The current user is notified.

You can also click on Remote Console Share but you will need to purchase another license key for the functionality of having multiple users using the remote console at the same time.

One more solution:

If you’re using HP iLO (Integrated lights out) and get this message it is because another user is either using the iLO or somehow it’s locked up.

One way to get around this is to reset it under the web settings for the iLO if you have access to it. Under the System Status tab, you can go into diagnostics and there is a button to reset iLO2.

Note that will kick off anyone currently using it, but who cares as long as it helps you right?

Control what happens when you start Outlook

1, In the folder that Outlook.exe is installed in, right-click the Microsoft Outlook icon, drag it to the desktop, and then click Create Shortcuts Here on the shortcut menu. Outlook.exe is usually located in the C:\Program Files\Microsoft Office\ Office folder.

2, Right-click on the desktop shortcut you just created, and then click Properties.

3, Click the Shortcut tab.

4, In the Target box, type a space after the path, and then type one or more of the following command-line options.

Paths that include spaces between words, such as C:\Program Files, must be enclosed in quotation marks (“) and are case sensitive. To specify a path in Outlook, precede the path with “Outlook:\\”.

For example, to open the My Documents folder when you start Outlook, the complete entry would be “C:\Program Files\Microsoft Office\Outlook.exe” /select “C:\My Documents”.

Outlook Web Access segmentation in Exchange 2000 Server

OWA segmentation provides the ability to selectively enable features of OWA. For example, you can disable or enable mail, Calendaring, Contacts, public folders, Calendar reminders, new mail notification, and MS IE 5 support according to service offering. Administrators can segment OWA into different support offerings in Exchange 2000 Server Service Pack 2 (SP2) and later. You can segment OWA on a per-server or a per-user basis. Per-user settings override per-server settings, if both are in place.

A Few Important Troubleshooting Tips

1, When you are finished with your mail you must click the Log Off icon AND go to the FILE menu and choose either Quit or Close. If you don’t do both steps, you leave your e-mail account open to the next web browser user!

2, If OWA appears to freeze while you are using it, click on the Refresh or Reload icon on the top of the browser window. This should get things going again. If that doesn’t work, press Control N on your keyboard and a new page should appear. If you have tried the first two options and the computer is still frozen, click the browser window Close button.

HP Chairman and CEO Carly Fiorina Steps Down

就象七年前Compaq宣布收购DEC,就象三年半以前HP宣布合并Compaq,今天早上我们又听到一个breaking news。

卡莉把朗讯科技从AT&T分拆出来后,AT&T和朗讯在市场上的声音就越来越弱、分额越来越小;卡莉把安捷伦从HP分拆出来以后,一个以创新为己任的硅谷的标志,变成了一个做仪器的小公司和一个连续三年没有新产品出台的硬件公司;卡莉消灭了一个对手,让Hewlett和Parkard的后人黯然离开了HP的董事会,让Michael Capellas背着沉沉的遣散费接管WorldCom去了;卡莉在消灭Compaq的同时也顺带消灭了DEC的众多标志性产品,譬如Alpha、Open VMS、Tru64 UNIX,还有Tandem。

卡莉,春节快乐,一路走好。
