Tomcat Tuckey UrlRewrite to rule issue

Question

My problem is this, I have issues with similar looking rules in my urewrite.xml file, in the fact that the first rule will work, but similar rules that follow will not. Here is an example:

<rule>
<from>Porsche-911_991-3.4_Carrera.jsp</from>
<to>cars.jsp?makeID=640&amp;modelID=3747</to>
</rule>

<rule>
<from>Test-Porsche-911_991-3.4_Carrera.jsp</from>
<to>test.jsp?makeID=640&amp;modelID=3747</to>
</rule>

The first rule works, the second does not, the reason for which escapes me. If I manually visit test.jsp?makeID=640&modelID=3747 the page works, if I try Test-Porsche-911_991-3.4_Carrera.jsp the page does not appear, simply generates an error log specifying parameters are missing.

I hope somebody can assist me before I pull all my hair out.

Answer 1

The matching text of the first rule, Porsche-911_991-3.4_Carrera.jsp, is a substring of the matching text of the second rule. As a result, the second URL is gone.

Use the caret metacharacter to distinguish between the two URLs:

<rule>
  <from>^/Porsche-911_991-3.4_Carrera.jsp</from>
  <to>cars.jsp?makeID=640&amp;modelID=3747</to>
</rule>

<rule>
  <from>^/Test-Porsche-911_991-3.4_Carrera.jsp</from>
  <to>test.jsp?makeID=640&amp;modelID=3747</to>
</rule>

Reversing the order to put the more specific URL first would work as well:

<rule>
  <from>Test-Porsche-911_991-3.4_Carrera.jsp</from>
  <to>test.jsp?makeID=640&amp;modelID=3747</to>
</rule>

<rule>
  <from>Porsche-911_991-3.4_Carrera.jsp</from>
  <to>cars.jsp?makeID=640&amp;modelID=3747</to>
</rule>
