BASE HREF details needed

Posted on 1998-01-08
Last Modified: 2010-05-19
I want to specify base href in an online .html file.  Specifically, I want to set base href to a local (hard drive) folder, which visitors can download from the net as a self-extracting archive.
What I need is the EXACT format for the tag (BASE HREF=?????????)  <BASE HREF=?????????>.
FYI  I have a routine in place which extracts the path from a cookie, and writes the BASE HREF tag using JavaScript.

The format is : <BASE HREF="">

Sorry but I can't accept this answer, Sandburg, because (as I said)  I need to set BASE HREF to a LOCAL folder (i.e. on the user's hard drive).  I presume the format would be something like <BASE  HREF='file:///C|/Download/'>, but I posted the question to get precise guidance on formatting the tag.

the base href you type : <BASE HREF="file:///C|/Download/"> is right for a base href to a folder on the hard-drive

For NN it's <BASE HREF="file:///C|/www/trybaseh.htm">
For MSIE it's <BASE HREF="file:C:www/trybaseh.htm">

I answered my own question. What do you know????

both MSIE and NN support file:/// and then the exact path, where : is converted to | and backslashes become slashes.
The more recent versions of MSIE and NN accept the standard DOS format, as well - but older versions accept the file:///C|... only.

you can't use "<BASE HREF=>" on a local disk.
you have to move your files to a server.

You most certainly CAN set base href to a local disk.  I have a self-extracting zip archive available to my online clients, so that 400 kb or so of graphic and htm files download and unzip to their hard drive.  The target directory name is stored in a cookie, so whenever they visit the WWW site the parent frame reads the cookie and sets base href to the correct local directory.  As of today I have this working flawlessly in NN and MSIE.  The comments from Christian W. were most helpful and  I would like him to have the points.

You *can* set the BASE HREF to a local file location, but it's pretty haphazard because not all users' hard drives will be configured similarly.  Your page will only  "work" on a certain platform and OS, and then only if the user has a "standard" configuration (hasn't done any custom installs).

Since you really can't control the file structure of users' drives, and since very few users will have a specific "fingerprint," it's not advisable.

You didn't say why you needed this.  Seems to me as long as all your links and image references are relative, it doesn't matter where they extract the archive.

Regarding the comment from JShamlin,
Is there a way in Java or JavaScript to test for the client's operating system (ie WIN or W95, etc)??  I feel confident that the script I've written for saving BASE HREF of the local directory in a cookie in the WINDOWS environment works!  If there's a way to screen for OS, I can warn those non-windows OS client's that the batch download is not guaranteed to work.

Regarding the question from gwalters,
The reason for offering a batch download of graphic and htm files called at various times into various frames of the parent document (on the server) is to save time for frequent users of the site.  If you want to check out how it works, the URL is
I would love it if some of you would try the batch download option (called 'TURBO') and let me know how it works on your system!

"<BASE HREF="c:\directory" will do just fine.
