Below is a table of Response Properties along with examples and explanations.

Response Properties Buffer Response.Buffer = true
Allows for the buffering of output CacheControl Response.CacheControl="Public"
Sets Cache to "Public" or "Private" CharSet Response.CharSet="windows-1252"
Sets the ISO character set ContentType Response.ContentType="text/HTML"
Specifies the output mime type (text/html, text/plain, GIF, JPG) Expires Response.Expires=60
Sets page expiration in minutes ExpiresAbsolute Response.ExpiresAbsolute=#January 31, 2003 13:00:00#
Sets time certain for page to expire IsClientConnected if (Response.IsClientConnected==true) { }
Determines if client is still connected PICS ((See Explanation))
Platform for Internet Content Selection Status Response.Status="401 Unauthorized"
Sets Page Status

You are not required to set, alter, or utilize a single Response Property if you don't want to. Having said that, they can be handy once in while. I've demonstrated all but two Properties in the script below.

By the way, set your properties BEFORE you begin output to the client.

Get Started:

Below is the ASP script for Lesson 07.

<%@LANGUAGE="JavaScript"%>
<%
Response.Buffer=true
Response.CacheControl="Private" 
Response.CharSet="windows-1252"
Response.ContentType="text/HTML"
Response.Expires=-1
Response.Status="200 OK"
%>
<HTML>
<BODY>
<%
if (Response.IsClientConnected==true)
	{
	Response.Write("The client is connected.<BR>")
	}
else
	{
	Response.End()
	}
%>
<TABLE BORDER="2">
<TR>
<%
for (x=1;x<=200;x++)
	{
	Response.Write("<TD>" + x + " </TD>\r")
	if (x%10==0)
		{
		Response.Clear()
		}
	if (x%4==0)
		{
		Response.Write("</TR></TABLE>\r")
		Response.Write("<TABLE BORDER=\"2\">")
		Response.Write("\r<TR>")
		Response.Flush()
		}
	}
%>
</TR></TABLE>
</BODY>
</HTML>

Click Here to run the script in a new window. After you click onto the link, really study the numbers. See if you notice anything weird about the page, like missing numbers.

Response.Buffer:

Let's take the Properties in order of appearance in our script. Response.Buffer allows us to control the output via Response.Flush() and Response.Clear(). If you haven't already, click onto the link to run the script. You'll get a strange output with some of the numbers missing. The missing numbers are thanks to Response.Clear(). You might notice that Response.Flush() slows down the server TREMENDOUSLY. Don't use this method without a reason.

Response.CacheControl:

CacheControl gives you the power to authorize proxy servers to keep your page in cache. (That would be the "Public" setting.) Likewise, it allows you to disallow proxy servers from caching your page. (That would be the "Private" setting). The default is "Private."

Response.CharSet:

CharSet allows you to specify the character set, for example: "ISO 8859-1".

Response.ContentType:

ContentType allows you to indicate the mime type of the output. For example there is text/plain and text/html. There is also GIF and JPEG.

Response.Expires:

Expires allows you set an expiration time for the page. By setting the Expires property to -1, you are saying the page expired one minute before it was delivered. The browser will (hopefully) not store it in cache, but rather make a separate request to the server before re-displaying the page.

Response.Status:

If tomorrow Congress were to pass a law forbidding the use of Response.Status, I think life would go on. If it makes you happy, use it.

Response.IsClientConnected:

IsClientConnected does exactly what it says. It returns a Boolean value that you can use in an "if" statement.

Response.PICS:

PICS stands for Platform for Internet Content Selection. It allows pages to be rated for the presence of violence, sexuality, language and nudity. There are services on the internet to rate your site. I've never used one. I found a sample PICS string on the internet and I converted to JavaScript.

Response.PICS("(PICS-1.1 <http://www.rsac.org/ratingv01.html> labels on \"1997.01.05T08:15-0500\" until \"1999.12.31T23:59-0000\" ratings (v 0 s 0 l 0 n 0))")

It's a long string and your browser may have wrapped the text down to a second line. If that's the case, then you have to pretend that the entire PICS string is on one line.

Response.ExpiresAbsolute:

I did not demonstrate ExpiresAbsolute in the script because I already used Response.Expires. ExpiresAbsolute does exactly the same thing as Expires, except it uses a date and time certain. (I couldn't see using both in the same script.) The only thing I would point out is the pound signs (#) at the beginning and and of the date.

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线

暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。

艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。

《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
