  Help! Regular Expressions Reply Contact Here is the scenario.  We have ARR receiving requests for 2 distinct hostnames.  We'll call then http://WEBAPP1 and http://WEBAPP2.  Both host names have the same IP and resolve to the same ARR server. WEBAPP1 and WEBAPP2 have 2 servers behind them.  In ARR I have 4 web farms.  WEBAPP1A WEBAPP1B WEBAPP2A WEBAPP2B In my URL Rewrite rules, at the bottom is WEBAPP1A with a * wildcard.  Everything that comes in to WEBAPP1 goes to WEBAPP1A by default. The next rule is WEBAPP1B.  It is a * wildcard rule with conditions.  If you go to WEBAPP1/condition.htm (this is the REQUEST_URI in the condition) then you get routed to server WEBAPP1B.  Otherwise you get routed to server WEBAPP1A.   Now this same ARR hosts WEBAPP2 - different host name. I can create the next rule as a * wildcard and add a condition with HTTP_HOST to qualify the host name as WEBAPP2.  This would be the default location for WEBAPP2 urls. Now when I to route to WEBAPP2B, and I want to have multiple REQUEST_URIs in the conditions, I need to qualify the rule pattern with a regular expression to single out the host name.  So if I want WEBAPP2/condition.htm to go to WEBAPP2B, I need to know how to write this expression.  There doesn't seem to be a way to do this with * wildcards.  Any and all help is greatly appeciated.

  Re: Help! Regular Expressions Reply Contact Thanks for the reply!  Here are the current rules. The top-most rule should be invoked for the host name WEBAPPUAT with conditions for specific applications.  Using a wildard rule, I tried to qualify the hostname with *webappuat* or http://webappuat*, but this did not work.   -Alan Levine   <rewrite>             <globalRules>                 <clear />                 <rule name="ARR_Core2Uat_loadbalance" enabled="true" patternSyntax="Wildcard" stopProcessing="true">                     <match url="*webappuat*" />                     <conditions logicalGrouping="MatchAny">                         <add input="{REQUEST_URI}" pattern="/hello2.txt" />                     </conditions>                     <action type="Rewrite" url="http://Core2Uat/{R:0}" />                 </rule>                 <rule name="ARR_Core1Uat_loadbalance" enabled="true" patternSyntax="Wildcard" stopProcessing="true">                     <match url="*" />                     <conditions logicalGrouping="MatchAll">                         <add input="{HTTP_HOST}" pattern="webappuat" />                     </conditions>                     <action type="Rewrite" url="http://Core1Uat/{R:0}" />                 </rule>                 <rule name="ARR_Core2Int_loadbalance" enabled="true" patternSyntax="Wildcard" stopProcessing="true">                     <match url="*" />                     <conditions logicalGrouping="MatchAny">                         <add input="{REQUEST_URI}" pattern="/hello2.txt" />                         <add input="{REQUEST_URI}" pattern="/testtest/*" />                     </conditions>                     <action type="Rewrite" url="http://Core2Int/{R:0}" />                 </rule>                 <rule name="ARR_Core1Int_loadbalance" enabled="true" patternSyntax="Wildcard" stopProcessing="true">                     <match url="*" />                     <conditions logicalGrouping="MatchAll" />                     <action type="Rewrite" url="http://Core1Int/{R:0}" />                 </rule>             </globalRules>         </rewrite>
