问题
I was trying to prettify URLs for dynamically generated pages on my website, so that when a user visited the virtual URL topicview/interesting-user-friendly-text he would really be seeing, under the hood, topicview.php?topicid=123
I added the necessary code to my .htaccess file to replace the topicview/interesting-text part of the URL with topicview.php?topicname=interesting-test, but the Regex kept misfiring.
So, I changed the Regex to return the entire URL so I could see why it wasn't working with this code:
#Allow for topicview/topic-name URLs
RewriteRule (.+)$ topicview.php?topicname=$1 [L]
I then visited topicview/user-friendly-text. I'm not sure if this is unique to Network Solutions hosting, however, when I examined the topicname GET paramter, I got this string in return:
data/1/2/323/232/823238/user/999999/htdocs/topicview.php
This URL was not displayed in the topicname GET parameter, just a regular file, like index.php or topicview.php, if I just visit the URL index.php or topicview.php
Why is the URL internally represented like this to the Apache server, and how can I rewrite my mod_rewrite code to get a more user friendly virtual URL for the topicview.php?topicid=1 pages?
thanks

For the friendly URL try this in your .htaccess file
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/?topicview/([^/.*]+)/?$ topicview.php?topicname=$1 [L,QSA]

The pattern matched in a RewriteRule is normally the similar to the REQUEST_URI but the behaviour you describe suggests it is matching against the REQUEST_FILENAME or something similar which is the file path including the full document root.
This would suggest your RewriteRule is not in your .htaccess file but instead in your or rules in the Apache config files, correct?
Instead you should try getting the value you want using a RewriteCond so you can guarantee you are matching against the REQUEST_URI, for example:
RewriteCond %{REQUEST_URI} ^(.*)$
RewriteRule . topicview.php?topicname=%1 [L]
Note the %1 rather than $1 which allows you to use values captured in the RewriteCond.
