I am using UrlRewriter.NET for urlrewriting...how do i write the [regular expression](https://www.mindstick.com/articles/11909/java-regex-or-regular-expression-in-java) for

http://localhost:2731/CitiZenJourNalism/ViewProfile.aspx?uid=3eb5bf69-1047-4936-9885-8ff41d45646f

in this [format](https://www.mindstick.com/forum/162083/how-to-convert-ost-files-into-pst-format) <rewrite [url](https://www.mindstick.com/forum/436/url-redirection) = "~/ViewProfile/([^/.]+)" to="~/ViewProfile.aspx?uid=$1" />

what should be the rewrite url for http://localhost:2731/CitiZenJourNalism/Reports.aspx?cat=local&id=6

Hi John, \

try this:

<rewrite url="~/Reports/(.+)/(.+)" to="~/Reports.aspx?cat=$1&amp;id=$2" />
