Bug 63696

Summary: uriworkermap does not work properly if it has /* pattern
Product: Tomcat Connectors Reporter: kimc.log
Component: isapiAssignee: Tomcat Developers Mailing List <dev>
Status: RESOLVED INVALID    
Severity: normal    
Priority: P2    
Version: 1.2.46   
Target Milestone: ---   
Hardware: PC   
OS: All   

Description kimc.log 2019-08-26 04:02:42 UTC 
I configured uriworkermap.properties like the following.

* uriworkermap.properties
/tomcat*=tomcat
/*=root

I wanted them to act like that first /tomcat pattern send all the request starting with that pattern to tomcat worker and the other pattern send to root worker which has another web application.
But the result always choose /* pattern... why?
You can see the logs below, Found a wildchar match '/*=root'
Please tell me if there is another way to do what I want?

* workers.properties
worker.list=tomcat,root
worker.tomcat.type=ajp13
worker.tomcat.host=localhost
worker.tomcat.port=10190
worker.root.type=ajp13
worker.root.host=localhost
worker.root.port=10290

Comment 1 Rainer Jung 2019-08-26 08:19:59 UTC 
As far as I remember, the isapi redirector support some kind of virtual hosting in IIS by first prefixing the URL with the local server name before mapping the request using uriworkermap.properties. Only if it can't map that URI, it will next try the raw URI without prefixed vhost.

So the log tells us, that it first tries to map

/localhost:48080/tomcat/test.jsp

and that URI matches the root map, not the tomcat map.

I guess port 48080 is something you configured. If that is stable, you could try the follwoing rules instead in uriworkermap.properties:

/localhost:48080/tomcat*=tomcat
/localhost:48080/*=root

Any non-root context mapping would not require the vhost prefix in the rules, because it would never match a /HOST:PORT/ prefixed URI. Only /* unfortunately matches it.

Alternatively you can stay with your config but add another first rule (exclusion rule starting with an exclamation mark):

!/localhost:48080/tomcat*=root

You can read a bit about the IIS vhost feature and maps under:

http://tomcat.apache.org/connectors-doc/reference/uriworkermap.html#Virtual_host_integration
