Hi,

I want to redirect https://xyz.com to https://www.xyz.com, but somehow its not working.
we are using mod_rewrite module with apache.

Could you please direct us how to do it..........


Also its seems to be some ssl header limitation. Could you demonstrate the data flow difference between https and http



Regards.

An example of how to achieve this would be:

        RewriteEngine on
        RewriteCond %{SSL} !^off$
        RewriteRule ^(.*)$      https://%{HTTP_HOST}$1

The rewrite rule for the xyz.com to www.xyz.com would be something like this:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$      https://www.%{HTTP_HOST}$1 [L]

It does work ( i have tested it on a live setup ) but please ensure that these rewrite rules are in the site configuration for the SSL site not the site running on port 80.

Well we are using more than one ports in apache server.


Is there any way from which this rule only confines upto 443 port.(i.e can we use AND loop in RewriteCondition--- (443)&&(!^www\.))



Please suggest..........

You can add another RewriteCond so
RewriteEngine on
RewriteCond %{HTTPS} !^off$
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$      https://www.%{HTTP_HOST}$1 [L]

This will redirect to the www. version if they are using https and aren't going to the www. version.

I think i may have just worked out what you are trying to achieve, if your certificate isn't valid for the non www. version they will still get the warning message and have to accept it before this redirect will work to direct the to the domain for which the cert if valid.

When the https header request flows then firstly it forward to CA url............ so if CA find exact url then simply throws error of bad certificate...................so rewrite process which should be taken place after ssl authentication remain unhit..........

And after accepting "This Connection is Untrusted" message, the redirection rule is working perfectly.



But I require this before all that.........................

Just clearing my post:


we have bought certificate for https://www.xyz.com and not for https://xyz.com.


So, we want https://xyz.com request to redirect  on https://www.xyz.com..............
but on hitting https://xyz.com, apache takes us to the message(ssl untrusted). which we want to bypass..

Hi pradeep,

I am not sure if this is possible at all.  Apologies for my naiveness.

If we were to look at the situation, client type in https://xyz.com/ and hit your apache, then during ssl handshake, the Browser (and not Apache) that is complaining about the certificate name mistmatch.  Note that the certificate common name is www.xyz.com, but the request is going to xyz.com.

excellent info here:
http://publib.boulder.ibm.com/infocenter/tivihelp/v2r1/index.jsp?topic=/com.ibm.itame2.doc_5.1/ss7aumst18.htm

just my 1 cents.

Yes this can not be acheived as the ssl request firstly goes to CA site.
The only way is to use wild card certificate for whole domain.
