Reverse proxy in IIS to local TomCat

Question

IIS has several websites:

domain1.com
a.domain2.com
b.domain2.com

There is also a TomCat running on

localhost:8087

The challenge is how to expose the TomCat externally as

b.domain2.com

What I did:

Enabled Proxy in ARR in IIS

Added Reverse Proxy URL Rewrite rules on b.domain2.com

<rewrite>
    <rules>
        <rule name="ReverseProxyInboundRule1" stopProcessing="true">
            <match url="(.*)" />
            <action type="Rewrite" url="http://localhost:8087/{R:1}" />
        </rule>
      </rules>
    <outboundRules>
        <rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml1" >
            <match filterByTags="A, Form, Img" pattern="^http(s)?://localhost:8087/(.*)" />
            <action type="Rewrite" value="http{R:1}://femiscan.a2itsolutionsllc.com/{R:2}" />
        </rule>

        <preConditions>
            <preCondition name="ResponseIsHtml1">
                <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
            </preCondition>
        </preConditions>
    </outboundRules>
</rewrite>

What I see:

Locally if I navigate to

http://b.domain2.com

my browser shows TomCat website as

http://localhost:8087

(Why?)

Externally if I navigate in Chrome to

http://b.domain2.com

it tries to tunnel to

http://localhost:8087

If I navigate in IE it returns 500 error (Fiddler: HTTP/1.1 500 URL Rewrite Module Error.)

Question: What am I doing wrong? Can it be done and how?

This might be better addressed in the SuperUser SE. – mdpc Dec 20 '12 at 06:07 — mdpc, Dec 20 '12 at 06:07

Your Action is set to Rewrite so it is rewriting the URL.

In IIS Manager:

Right-click Server Farms, click "Create Server Farm". Give it some name.
Put the fully-qualified domain name to your Tomcat instance in the "Server name or address" field
Click "Advanced settings...", expand "applicationRequestRouting" and change httpPort to 8087
Click "Yes" when prompted to create a rewrite rule
Click the newly created farm under "Server Farms" in the pane on the left side of the window
Open "Routing Rules" on the Server Farm feature view page
Click the "URL Rewrite..." link on the right pane
Remove the old attempted Tomcat rewrite rule
Click "Add Rule(s)..." at the top of the right pane, choose "Blank rule"
Give it a name
In the Match URL pane:
- Requested URL: Matches the Pattern
- Using: Regular Expressions
- Pattern: *
Expand the Conditions pane, click "Add"
- Condition input: {HTTP_HOST}
- Check if input string: Matches the pattern
- Pattern: b.domain2.com
- Check Ignore Case
In the Action pane:
- Action type: Route to Server Farm
- Scheme: http://
- Server farm: (the name of your server farm)
- Path: {R:1} (NOTE: This may need some tinkering but judging by your example it should work)
Click "Apply" on the right pane and your

The only thing that I did different was making the URL pattern `.*` instead of `*` in the Match URL pane, and everything worked perfectly. — Mehmet Ataş, Jan 11 '15 at 20:53
