I use url rewriting for my web site. I did settings on IIS and it works on server. But it doesn't work on localhost. It is normal because there is no page with rewrited url in my project files. How can I solve this problem? I use cassini server when I develop my project. Should I use local IIS in my computer? You can see here my url rewriting roles in web.config file:\[code\] <system.webServer> <modules runAllManagedModulesForAllRequests="true" /> <rewrite> <outboundRules> <rule name="OutboundRewriteUserFriendlyURL1" preCondition="ResponseIsHtml1"> <match filterByTags="A, Form, Img" pattern="^(.*/)ProductDetail\.aspx\?prid=([^=&]+)&(?:amp?product=([^=&]+)$" /> <action type="Rewrite" value="http://stackoverflow.com/questions/13866093/{R:1}ProductDetail/{R:2}/{R:3}/" /> </rule> <preConditions> <preCondition name="ResponseIsHtml1"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" /> </preCondition> </preConditions> </outboundRules> <rules> <rule name="RewriteUserFriendlyURL1" stopProcessing="true"> <match url="^urun/([^/]+)/([^/]+)/?$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="ProductDetail.aspx?prid={R:1}&product={R:2}" /> </rule> </rules> </rewrite> <urlCompression doDynamicCompression="false" /> </system.webServer>\[/code\]
