I have eccube 4.x project which is under development. Suppose I want to use a link tag to go to an external web page (eg. www.google.com). clicking this link will add it to project directory (eccube-4.0.4 / www.google.com) so I cant go to www.google.com. How can I resolve this issue? I am an English user. I also used a Google translator to translate the question into Japanese. Thank you very much. I am new so appreciate the help.

Suppose in logo.twig by clicking the logo the default code is:
<a href="{{url('homepage')}}">
{{BaseInfo.shop_name}}
</a>
which works but I want to go to Or Any Other Google Webpages Outside My Project When Clicking Logo, So Change:
<A Href="{{ Url(' www.Google.Com') }}">
{{BaseInfo.Shop_name}}
</A>
But Then Page is not found because it adds my project directory with www.google.com.
It tries to reach: http://49.xxx.xxx.xxx/eccube-4.0.4/404?bind=https://www.google .com /

Doesn't specifying from https solve the problem?
Describe it as https://www.google.com/

Can I confirm the actual writing I gave as "www.google.com"?

"{{ url('homepage') }}" function outputs your directory.
Is it inconvenient to write? so <a href="https://www.google.com/">

I'm not sure about this English.
