基本思路 利用表单将用户提交的搜索关键字存储在变量中，并提交给ASP脚本处理。利用ASP内建的“REQUEST”对象获取变量中的关键字符，随后用“RESPONSE”的“REDIRECT”函数将关键字符转向提交到其他的诸如搜狐、网易等专业搜索引擎中，即可得出搜索结果。使得访客在自己的主页上就可方便地使用各大搜索引擎，无需登录其主页面。
第一步 创建搜索引擎的主页面。在HTML文件
的＜ body＞和＜ /body＞之间加入代码如下：
＜ form name="form1" method="post" action="search.asp"＞
＜ div align="center"＞请选择您喜欢的搜索引擎＜ br＞＜ br＞
＜ select name="select" size="1"＞
＜ option＞搜狐＜ /option＞
＜ option＞新浪(北京站)＜ /option＞
＜ option＞网易＜ /option＞
＜ /select＞＜ br＞＜ br＞
请键入您要查询的关键字＜ br＞
＜ input type="text" name="textfield"＞
＜ br＞＜ br＞
＜ input type="submit" name="Submit" style="color:#CC0033background-color:#fffffffont-size:9ptborder:#CC0033 1px solidheight:18px"value="搜 索"＞
＜ /form＞
在此，我们提供了搜狐、新浪、网易3种搜索引擎供用户选择，用户键入关键字串后，表单将请求提交到后台的 search.asp 处理。
第二步 编写后台的ASP程序。在HTML文件的＜ body＞和＜ /body＞之间加入下列代码：
＜ % if request.form("select")="搜狐" then response.redirect("
sitesearch.jsp?key_word="&&request.form("textfield")) end if
if request.form("select")="新浪（北京站）" then response.redirect("
sitesearch.jsp?key_word="&&request.form("textfield")) end if
if request.form("select")="网易" then response.redirect(""&&request.form("textfield")) end if
%＞
在实现提交搜索字串到其他搜索引擎时，很关键的一点就是要明白这些搜索引擎所使用的查询格式。如搜狐用的就是“”搜索字串 。我们只需平时在使用这些搜索引擎时注意一下，给出搜索结果时把IE地址栏中的地址记录下来分析，去掉后面的诸如“%C1%F5%……”字符(这是我们提交的搜索字串转换成的字符)，即可得到查询格式。
另外，很多搜索引擎使用了分类查找。可细分为“网站”、“网页”、“新闻”等类别，每一种类的查询格式均不相同，读者可以使用更多的IF语句建立选择项，实现同一搜索引擎内搜索种类的细分。
同理，我们还可把这个程序进行扩充，把其他的搜索引擎加入，使其功能更为强大。
