Ask an Apache mailing list. You will get more help...

Yes, it is.

No, that wouldn't work too well, as it redirect every request to the
script. In general you want your rewrite rules to be as narrow as you
can. The pattern ^/\w+\/?/$ probably makes more sense.

I would also modify my_profile.php so it finds the user based on the
user name instead of doing a redirect to the page with the user id.
Don't really see a reason to do it in two steps.

Yes, that is better, thank you.

I think you might have misunderstood what the my_profile.php page is.
It does not
redirect, it _is_ the user profile page, but based on the user_id as
given in the query
string (which is encoded in the query string, so decoded on the page),
it can get all
the information about the user from the database - it's a simple
database-driven page.

I understood you just fine. What you are planning to do is to find the
user id based on the given user name in redirect_user.p hp, then
redirect to my_profile.php, which look up the user record using the id.
What I suggested was to look up the user record using the user name in
my_profile.php. There is no point in doing a redirect to the page when
you can rewrite directly to it.

Re: seeking mod_rewrite solution

Oh! Duh! Yes, of course - that makes perfect sense. I guess the only
reason I was thinking about using an intermediary redirect page was to
do any other pre-processing that might be necessary. For example, if
the "name" is "admin", then I would have the redirect page redirect the
user to the actual admin folder since in this case, this is not a
user's profile page, but an administrator trying to access the backend.
But, I guess this should probably be done using a RewriteCond?
Something like:

RewriteCond %{REQUEST_URI} !^admin.*$

Or something like that (I'm not too familiar with the syntax, although
I am somewhat familiar with regular expressions).

It's easier to handle this special case by putting another rewrite rule
ahead of the one dealing with the profile page.

RewriteRule ^/admin/?$ /admin_page.php [L]
RewriteRule ...

The [L] flag tells mod_rewrite to not apply the subsequent rules.

Re: seeking mod_rewrite solution

Alright, I think I've got everything squared away, but now for the
potentially annoying part - how do I run the thing? Is it simply a
matter of including

RewriteEngine On
RewriteRule ^/admin\/?/$ /admin/index.php
RewriteRule ^/\w+\/?/$ /my_profile.php? user_name=$1

in the .htaccess file? Or do I need to include more in the .htaccess
file, or does this code have to go somewhere else besides the .htaccess
file? Is the mod_rewrite module already built in (I think it is)?
I've been trying to read about the mod_rewrite module on
http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html, but I'm still
confused as to how to get the thing actually working. Ideally, the
complexity of a task should somewhat reflect the complexity of
implementing that task, but I don't know if that's the case here.

Re: seeking mod_rewrite solution

Ok, I'm beginning to understand the mod_rewrite module better. I
discovered the following important information. The RewriteEngine and
RewriteRule directives (which I will be using, possibly along with the
RewriteBase directive) are "Extensions ". And the Apache server
documentation says this about "Extensions ":

A directive with "Extension" status is provided by one of the modules
included with the Apache server kit, but the module isn't normally
compiled into the server. To enable the directive and its
functionality, you will need to change the server build configuration
files and re-compile Apache.

So, does anyone know how I would "change the server build configuration
files and re-compile Apache."?

Joel,

Try an Apache newsgroup, like alt.apache.conf iguration. You don't have
to actually recompile Apache - just configure it correctly.
