get the base url in the code behind?

[Guest]

Hi;

I need to get the base url (what pages in my app are added to to make the
complete url). To do this when I have a request object it's a piece of cake -
I use http://www.davidthielen.info/programming/2006/10/base_url_in_an_.html

But I have an event handler for my HttpApplication. In that event handler I
create html pages. If those pages have images, I need to have links to the
images that I will serve up.

It seems to me this may be impossible. Because I may hit the site using
http://server while someone else uses http:///www.domain.com, etc. Is there a
way to do this?

Or am I right that it makes no sense because of aliases for the same machine?

Simply use "/" to use paths relative to the root. For example, a reference
to "/images/abc.gif" will work as long as your root has an images folder, so
whether they're on http://www.www.com/ or http://localhost/, both will
display correctly.

Thanks for Keith's input.

Hi Dave,

In addition to the site root specific path (start with "/"), you can also
use the Page.ResolveUrl("~/...") to get application root specific path.
Actually, for client browser, as long as it has requested the first page on
a website, it will record the base url (servername) and sequential
requests through root specific path ( start with "/...") can be correctly
resolved then.

Anyway, I think you're right that we can not get all the possible public
DNS name of our server(that will be used by different internet clients) in
the application itself.

Please feel free to post here if you have any further questions.

Sincerely,

Thank you both of you.

What I am doing is just "file.htm", not "/file.htm" and that seems to work
fine. I've created using localhost as my server then displayed using the
server name and it all works great.
