Redirect to non www to www version

[nidheesh ks, modificado hace 12 años.]

Hi ,

I have multiple portal instances.
For a instance Ii gave virtual host without "www", then created an organization in the instance and I gave virtual host with "www" .
Now I want all my request to be redirected to "www" version if at all the user does'nt enter it in the url

Thanks in advance,

Nidheesh

I have no idea on how to do this on just tomcat or so.. but using a web server in front it can be done... see this http://www.scriptalicious.com/blog/2009/04/redirecting-www-to-non-www-using-htaccess/

Hi Ravi,
Thanks for you reply.
I understand what you mean , but for that i have to install apche on my server and proxy all request to tomcat right?.
I saw that when we type "liferay.com" in browser it gets redirected to "www.liferay.com", so I think there may be another way, or else liferay website is also doing the same with apache redirect.

Thanks

You are right..

I guess Liferay is using CDN.. check all the requests of a page when you open liferay.com

Hi,

For getting into a solution for this I tried creating a servlet filter which redirects all request coming without www to www.
Then I added it to liferay web.xml and the jar to lib folder and it seems working.
The only thing I missed is the order of the filter chain. Although my filter is defined first it is coming after vitual host filter I think, because www is getting appended but "web/org-name" is coming with it .

you can use the url rewriter. in the ROOT/WEB-INF, find the urlrewite.xml and add a new rule

<rule>
<name>Domain Name Check</name>
<condition name="host" operator="notequal">www.example.com</condition>
<from>^(.*)$</from>
<to type="redirect">http://www.example.com$1</to>
</rule>

Thank you qingsheng! You redirect everything except www.example.com to http://www.example.com.

I wanted to share my modified version, which redirects naked URLs to www URLs for single domain names like example.com.

        <rule>
                <name>Domain Name Check for example.com</name>
                <condition name="host" operator="equal">^example.com</condition>
                <from>^(.*)$</from>
                <to type="redirect">http://www.example.com$1</to>
        </rule>

This redirects non-www URLs to www URLs. So every pagehit that comes to example.org gets redirected to www.example.org. With this you can have multiple domains on one server.

I used below Redirect URL rule but its also redirect wrong url to my site.
For example its redirect zzzzzzz.example.com to my site.This is not what I want.Please suggest

<rule>
2 <name>Domain Name Check for example.com</name>
3 <condition name="host" operator="equal">^example.com</condition>
4 <from>^(.*)$</from>
5 <to type="redirect">http://www.example.com$1</to>
6 </rule>
