برای استفاده، ابتدا DLL مورد نظر را دانلود و به References‌ها اضافه می‌کنیم؛ دانلود فایل   Intelligencia.UrlRewriter.dll 

دانلود آخرین نسخه‌ی فایل از سایت مرجع:  urlrewriter.net

مرحله‌ی بعد تنظیمات Web.Config است که به صورت زیر می‌باشد:

<configuration>
  <configSections>
    <section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter" />
  </configSections>
  <system.web>
    <httpModules>
      <add type="Intelligencia.UrlRewriter.RewriterHttpModule,Intelligencia.UrlRewriter" name="UrlRewriter" />
    </httpModules>
  </system.web>
  <rewriter>
    <rewrite url="^.*-T([0-9]+)/?$*" to="~/ShowTerol.aspx?ID=$1" processing="stop" />
  </rewriter>
</configuration>

مرحله بعد تنظیم این است که کدام لینک‌ها بازنویسی شوند که در کد‌های بالا فقط یک مدل بازنویسی وجود دارد:

<rewrite url="^.*-T([0-9]+)/?$*" to="~/ShowTerol.aspx?ID=$1" processing="stop" />

و می‌گوید تمام لینک‌هایی را که در آخر آنها T- و عدد وجود دارد، به صفحه‌ی ShowTerol.aspx با یک کوئری استرینگ به نام ID که مقدار آن، همان عدد بعد حرف T میباشد بفرست.

یعنی این لینک را  

به این لینک تبدیل میکند                               

ShowTerol.aspx?ID=87

<rewrite url="^.*-p([0-9]+)/?$*" to="~/Products.aspx?p=$1" processing="stop"/>
<rewrite url="^.*-c([0-9]+)pa([0-9]+)/?$*" to="~/Default.aspx?c=$1&amp;pa=$2" processing="stop"/>
<rewrite url="^.*-c([0-9]+)/?$*" to="~/Default.aspx?c=$1" processing="stop"/>

الگوی تبدیلات توسط Regular Expansion
