URL Forwarding based on request parameters

I am using UrlRewriteFilter from http://www.tuckey.org/urlrewrite/. Mainly I am trying to get the following URL
http://domain/application/?param=value to redirect to
http://domain/application/?another_param=another_value (simply replacing the request param).
Below are my rule configuration that dosen't seem to work 

    <rule>
    <from>^(.*?param=value)$</from>
    <to type="forward">%{context-path}?another_param=another value</to>
</rule>

I have tried several other variations but that didn't seem to work either. any light shed on this issue would be much appreciated

Solution

  • I have been able to resolve the issue using the rule below

     <rule>
    <name>Selective redirect example redirect</name>
    <condition type="parameter" name="param" operator="equal">value</condition>
    <to type="forward">?another_param=another_value</to>
</rule>

    The key to the answer here is using the conditions rather than depending on the rule to capture the request, in my case I needed only to apply the rule when a certain param value is met. The second part of the answer is removing the <from> tag, and hence all the requests that fulfill the condition will be redirected to the same source page.
