Redirect https to http in Spring - http

Question

I have configured SSL into my application running on Tomcat using the standard procedures. I have modified the server.xml file and web.xml to enforce the use of https in every request. I am supposed to do one of the 2 things.
1) The redirection that is taking place is a 302 redirect. How can I make this as a 301 redirect? This 302 redirect is not allowing Google robots to crawl my site
OR
2) Use a mechanism wherein the urls that I require to be http, are redirected from https to http.
I know Tomcat cannot automatically redirect from https to http once it is re-directed to http. I have added the following entry in web.xml to enable http access for the url that I require
<security-constraint>
<web-resource-collection>
<web-resource-name>SecureConnection</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>UnsecureConnection</web-resource-name>
<url-pattern>/Market/browseMarket.htm</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
However once Tomcat is redirected to https using the first block, it is unable to redirect back to http even though the second block exists.
I read in some articles to use URLRedirectFilter in the application to achieve. To achieve that, I added the following in web.xml
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
I have placed the urlrewrite.xml under WEB-INF, the contents of which are:
<urlrewrite>
<rule>
<from>Market/browseMarket.htm</from>
<to>http://%{server-name}%{request-uri}</to>
</rule>
</urlrewrite>
However, this doesn't seem to work and I still end up with https on that page.
Can someone help me with one of the above issues with a solution?
