How I can Built A-Z index site map in my website

最近有个客户问我如何实现A-Z索引站点导航，我的回答如下，

Based on my experence, it seems that you want to implement the function like these websites,

http://www.usa.gov/Agencies/Federal/All_Agencies/index.shtml

http://berkeley.edu/a-z/a.shtml

am I right?

If so, I think there are two ways could to do this,

1. You can refer above websites, just create a.htm, b.htm ... and z.htm, and put the associated links in each page;

2. Create a data table for storing the links, and use a-z as a parameter(QueryString) for get the associated links.  For example:

    http://ww.yourdomain.com/default.aspx?index=a

    http://ww.yourdomain.com/default.aspx?index=b

    ...

    http://ww.yourdomain.com/default.aspx?index=z
