We are currently running two tomcat servers on our machine, one for 9.7 and one fo 10.3. 

9.7 on port 8080, 10.3 on port 8084. 

In order to remove the port numbers from the URL, I am trying to configure the IIS isapi_redirect. I have configured the jakarta folder in IIS to point to the 10.3 tomcat installation folder and configured the properties files as follows. 

workers.properties

#
# Simple workers configuration file
# Check the JK Documentation of Tomcat for more information
#

ps=\\

# List all workers
worker.list=defworker,support

# Redefining the worker named defworker of type ajp13
worker.defworker.port=8080
worker.defworker.host=localhost
#worker.defworker.type=ajp13
worker.defworker.lbfactor=1
# Specify the size of the open connection cache.
#worker.defworker.cachesize

# Specifies the load balance factor when used with a load balancing worker.
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=defworker

# Redefining the worker named defworker of type ajp13
worker.support.port=8084
worker.support.host=localhost
#worker.support.type=ajp13
worker.support.lbfactor=1
# Specify the size of the open connection cache.
#worker.support.cachesize

uriworkermap.properties

#
# Simple uri worker map configuration file
# Check the JK Documentation of Tomcat for more information
#

#default.worker=defworker
#uniface.worker=defworker
#support.worker=support

# --- Worker mappings for Uniface ---
/uniface/*=defworker

/support/*=support

a correctly working URL for the 10.3 install is SERVER:8084/webapp/support/main, and I have copied the webapp.xml to support.xml so SERVER:8084/support/support/main also works. 

When I try any combination of what I think should be the URLs to use the IIS, I get errors in the isapi_redirect.log of 

[Wed Jan 29 14:05:54.015 2020] [9452:11940] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (1313): wrong message format 0x4854 from 127.0.0.1:8084

And the localhost_access_log of 

127.0.0.1 - - [29/Jan/2020:14:05:54 +0000] "-" 400 -

Using SERVER/support vs SERVER/uniface seems to successfully change which copy of Tomcat the logs are added to, so I THINK the worker properties are pointing to the right internal servers. 

So. 

1. Can anyone tell me what the 'correct' URL to translate SERVER:8084/webapp/support/main to go via IIS as per the above files is? 
2. Are the above files 'right'? 

Help!

Hello Iain

Do you really need IIS ?

Tomcat also has rewriting url options.

I copy some info below:

Documentation regarding rewriting in Tomcat:
host
https://tomcat.apache.org/tomcat-9.0-doc/config/host.html
valve
https://tomcat.apache.org/tomcat-9.0-doc/config/valve.html
rewrite rules
https://tomcat.apache.org/tomcat-9.0-doc/rewrite.html

In D:\\apache-tomcat-9.0.30\\conf file server.xml I opened up a valve
<Host name="mymachine.mydomain"  appBase="webapps_prod" unpackWARs="false" autoDeploy="false">
  <Valve className="org.apache.catalina.valves.rewrite.RewriteValve"/>
  <!-- Access log processes all example. Documentation at: /docs/config/valve.html
  Note: The pattern used is equivalent to using pattern="common" -->
 
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
  prefix="mymachine_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

In D:\\apache-tomcat-9.0.30\\conf\\Catalina\\mymachine.mydomain file rewrite.config with rules:
Simple examples
RewriteCond  %{REQUEST_URI}  ^/webtest97/(.+)/(.+)/$
RewriteRule ^/(.+[^/])/$ http://mymachine.mydomain:8080/$1 [R=301,L]
RewriteCond  %{REQUEST_URI}  ^/webtest10302/(.+)/(.+)/$
RewriteRule ^/(.+[^/])/$ http://mymachine.mydomain:8084/$1 [R=301,L]

Other more complicated examples
RewriteCond %{REQUEST_URI} ^/music$
RewriteRule ^/start$ /messenger/wrd/musicmain [L]
RewriteCond %{REQUEST_URI} ^/start$
RewriteRule ^/start$ /messenger/wrd/eimagedsp [L]
RewriteCond %{HTTP_REFERER} !(.*)/music(.*)$
RewriteCond %{HTTP_REFERER} !(.*)/messenger(.*)$
RewriteRule ^(.*)$ /error.htm [L]
RewriteCond %{REQUEST_URI} ^/(webserver|css|common|img|images|dspjs|index.htm|error.htm)(.*)$
RewriteRule ^(.*)$ /messenger$1 [L]
RewriteCond %{HTTP_REFERER} (.*)/start(.*)$
RewriteCond %{REQUEST_URI} ^/(.*)$
RewriteRule ^(.*)$ /messenger/wrd$1 [L]
RewriteCond %{HTTP_REFERER} (.*)/music(.*)$
RewriteCond %{REQUEST_URI} ^/(.*)$
RewriteRule ^(.*)$ /messenger/wrd$1 [L]
RewriteCond %{HTTP_REFERER} (.*)/messenger(.*)$
RewriteCond %{REQUEST_URI} ^/(.*)$
RewriteRule ^(.*)$ /messenger/wrd$1 [L]
messenger.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<Context override="true" swallowOutput="true" useNaming="false" docBase="D:\\apache-tomcat-9.0.2\\webapps_prod\\messenger">

<!--

and some xml files to specify where to find what

<Context docBase="D:\\uniface\\installations\\10302\\uniface\\webapps\\uniface\\webserver">

Hi Ian

Peter's solution would be a good alternative to avoid using IIS, however, if you still want to use isapi redirect then here's some suggestions

The files look fine, however I noticed you commented the worker.type=ajp13. I believe this is actually the 'protocol' that is used by the isapi_redirect, and it has a separate connector configuration in (both) your server.xml. By default the port number used for this connector is 8009, however, in my case for example it is 8083:

if you then point the worker.port to this connector, it should work

worker.defworker.port=8083
worker.defworker.host=localhost
worker.defworker.type=ajp13
worker.defworker.lbfactor=1

As for the the URL;

let's assume the following:

Tomcat uniface appliction URL -       http://localhost:8084/webapp/support/main

IIS website                                         http://localhost/applications

uriworkermap.properties:                  /applications/*=defworker

Then basically you should replace * with the tomcat uri except the host part, so something like this:

http://localhost/applications/webapp/support/main

Hopefully this helps, 

Best regards

Erik
