Domain Redirect Question

[nathan...@gmail.com]

Hello, I am trying to use UrlRewrite to forward all requests to
http://mydomain.com onto http://www.mydomain.com.

I have done the following steps according to what I have read. To note
I am using Resin 3.0.12

#1) I downloaded urlrewritefilter-2.4.tar.gz, I copied it into my
appropriate web context. Making sure when I untarred the file that
urlrewrite.xml existed beneath my WEB-INF folder, and the jar in the
tar was in my lib/ directory.

#2)I added the following to my web.xml file, within web-app but above
my servlet-mappings as instructed:

<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>

#3)I added the following rule to urlrewrite.xml

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

#3)I then stopped & started Resin, in my normal manner.

The website is served but I am not getting my redirects? Any
suggestions, or mistakes in the above process? Do I need to make any
adjustments to my resin.conf? It currently has an entry related to this
site as follows:

<host id='mydomain.com'>
<host-alias>www.mydomain.com</host-alias>
<web-app id='/'
document-directory="/data/local-sites/mydomain.com">
<session-config enable-cookies='false'/>
</web-app>
<access-log path='log/access.log'>
<rollover-period>2W</rollover-period>
</access-log>
</host>

If you add

<!-- sets up log level (will be logged to context log)
can be: TRACE, DEBUG, INFO, WARN, ERROR, FATAL -->
<init-param>
<param-name>logLevel</param-name>
<param-value>DEBUG</param-value>
</init-param>

to your <filter> conf what do you see in the logs? If the filter being started.

Cheers,
Paul.

Hi Paul,

after adding the above to my <filter> tag into my
/data/sites/www.mydomain.com/WEB-INF/web.xml.

I see the following lines in my debug.log.

[08:08:30.249]resin:import
'/data/sites/www.mydomain.com/WEB-INF/web.xml'
[08:08:30.261]filter-mapping /* -> UrlRewriteFilter
[08:08:30.261]filter-mapping /* -> UrlRewriteFilter
...
...
[08:08:49.599]org.tuckey.web.filters.urlrewrite.UrlRewriteFilter DEBUG:
filter init called
[08:08:49.600]org.tuckey.web.filters.urlrewrite.UrlRewriteFilter DEBUG:
calling destroy just in case we are being re-inited uncleanly
[08:08:49.600]org.tuckey.web.filters.urlrewrite.UrlRewriteFilter INFO:
destroy called

That is all I see that is different. Please let me know if you need
more of this file because I could supply the whole thing.

Here is an example of the /rewrite-status if that might help:

Running Status

Conf file urlrewrite.xml loaded Thu May 19 08:08:59 PDT 2005.
Conf file reload check disabled

Status path /rewrite-status.
Summary of urlrewrite.xml

In total there are 2 rules, 1 outbound rule and 1 condtion in the
configuration file.
Rule 0

The rule means that requests to /test/status/ will be redirected to
/rewrite-status
the url will be rewritten.

URL's matching /test/status/ will be redirected to /rewrite-status.

Domain Name Check (rule 1)

URL's matching http://mydomain.com/(.*) will be redirected to
http://www.mydomain.com/$1.

Given that the following condtion is met.

1. The host HTTP header matches the value mydomain.com

Outbound Rule 0

The outbound-rule specifies that when response.encodeURL is called
(if you are using JSTL c:url)
the url /rewrite-status will be rewritten to /test/status/.

The above rule and this outbound-rule means that end users should
never see the
url /rewrite-status only /test/status/ both in thier location bar
and in hyperlinks
in your pages.

Outbound URL's matching /rewrite-status will be rewritten to
/test/status/.

Please Note two changes from my first post, first #3 should be #4, :),
and I have also changed my rule to the following:

<rule>
<name>Domain Name Check</name>

<condition name="host" operator="equal">mydomain.com</condition>
<from>http://mydomain.com/(.*)</from>
<to type="permanent-redirect">http://www.mydomain.com/$1</to>
</rule>

Hi

Okay- got it all loaded as Nathan has. Ive set it to run at Debug. I'm
getting the same problem - I've set this rule to run -

<rule>
<from>^/servlet/ProductLister?queryType=([a-z]+)$</from>
<to>/servlet/ProductLister/queryType/$1</to>
</rule>

<rule>
<from>^/servlet/ProductLister/queryType/([a-z]+)$</from>
<to>/servlet/ProductLister?queryType=$1</to>
</rule>

I've tried it also without includin the /servlet part. And nothing is
happening. I review the logs - and the DEBUG from the UrlRewrite tells
me

-Filter Init Called
-Calling destroy just in case we are being re-inited uncleanly
-destroy called

But I can't any of the examples to work.

Please help :)

[Paul Tuckey]

It looks like the destroy method of the filter is being called out of
sequence, can you tell me what application server and version you are
using?

Cheers,
Paul.

[Paul]

Could you try setting the log level to TRACE also.

Note the rule should really look something like:

<rule>
<name>Domain Name Check</name>
<condition name="host" operator="equal">mydomain.com</condition>

<from>^(.*)$</from>

<to type="permanent-redirect">http://www.mydomain.com/$1</to>
</rule>

Cheers,
Paul.

Thanks Paul!

After changing my rule to the above. It is working for me in my test
environment. Although it is sometimes giving me an extra innocuous '/'.

To note I am using Resin 3.0.12.

[Paul Tuckey]

Just change your from to be <from>^/(.*)$</from>.

Cheers,
Paul.

All working on my side now. The only thing I changed was that I was
failing to escape a "?" symbol in one of my rules.

Superb piece of software. Thank you Paul :)

(Let me know where to send the donation). Its not a lot by I really
appreciate someone taking the time to donate software like this.

[Paul Tuckey]

There is a donation button on the bottom of http://tuckey.org/urlrewrite/

Any donation to help with hosting fees is much appreciated!


Thanks,
Paul.
