We still have two issues here. You have problems with .htaccess, but you also have questions to answer about *how* we can tell the difference between Drupal and Lyceum in the URL. I'd suggest that's the question to answer before fixing the .htaccess. The rewrites (ie, .htaccess) work by taking a clean URL and converting it into the physical server path for the file/request. So we need to work out what the clean URL's looks like, and how we can determine from the clean url whether we redirect to Lyceum or Drupal.

There are a number of approaches you could take, but the easiest (given that you already have a Drupal based site) is to make all lyceum urls be like myuser.mydomain.com/lyceum/... We'll then assume any url without the /lyceum/ part is Drupal.

I'm not sure this is what you want though. From your description it sounds like you want to take the approach that all Drupal urls will be www.mydomain.com or mydomain.com, and all Lyceum URLs will be myuser.mydomain.com. That is, Lyceum is anything other than www., and Drupal is always www. or simply no www. The problem with this is going to be the root of Lyceum would also be mydomain.com (ie, no www.), so now we'd have to handle each case, or each page that Lyceum uses with no subdomain prefix.

Again, decide on your approach, and then we can work on the .htacess rules.

Thanks for your help to this point Dave, I am happy to make some financial
contribution to you for any further assistance as I think you have gone
above
This is not necessary. I'm helping because I want to not for financial gain. I would suggest donating to the Lyceum project, but I don't think they accept donations.

Thanks so much for your reply Dave. I have reinstalled with latest nightly
and your breakdown of the various rules is very, very helpful besides the
fact that you have clearly outlined exactly the nub of the issue.

I am using Drupal clean URLs with path auto modification which outputs page
(node) specific URLs according to node name.

Eg
Drupal base url: http://www.mydomain.com/about_us This is a static site so there is no user URL save for the system admin.

My intention was for Lyceum to handle all blog functionality through
subdomains and as you correctly state the final line
RewriteRule ^(.*) lyceum/$1 [QSA,L]

rewrites all requests to the lyceum/portal.php

I am using 'user subdomains' as per
RewriteRule ^(.*) lyceum/$1 [QSA,L]

and things stand now where you indicate they would - that is all redirects
go to lyceum/

I also cannot load created user blogs via the assigned url eg
newblog.mysite.com and I am guessing this is due to the rewrite rules
currently in place.

above and beyond the call.

In your scenario I think the fundamental issue is how are you going to determine whether the URL gets treated as a lyceum URL or as a Drupal URL. This is important because your processing rules for each are different. In other words, what are the rules for Lyceum and Drupal url processing? What will Drupal URL's look like, and what will Lyceum URL's look like, and what do you want the user to see in the browser? If you can provide samples of the Drupal and Lyceum url's and how you want that URL rewritten it will be easier to help with the .htaccess rules.

I'm looking for something like:
Drupal base url: http://www.mydomain.com/index.php?q=1234
Drupal user url: http://www.mydomain.com/drupal/file1

Lyceum base url: http://www.mydomain.com/lyceum/......
Drupal user url: http://www.mydomain.com/.....

# Various rewrite rules.
<IfModule mod_rewrite.c>
RewriteEngine On RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*) http://%1/$1 [R,L]
These two lines handle any url requests to www.yourdomain.com and change it into yourdomain.com. In the case on lifehaiku we need this because we make use of Lyceums ability to store blogs like myblog.mydomain.com. Are you doing this on your site? If not remove those lines.

RewriteRule ^(.*) lyceum/$1 [QSA,L]
This last line basically says to redirect *all* requests to the lyceum directory. The L directive at the end says to stop processing the .htaccess file after this rule. That's a problem since now we're not doing any Drupal stuff that follows. So remove that last line. The problem now is that no lyceum
<SNIP>
# Rewrite current-style URLs of the form 'index.php?q=x'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
If the requested URL is not a file and it's not a directory then rewrite the url to the format index.php?q=xxxx. This is the Drupal processing. The problem again is that at no point have we determined a criteria for differentiating Drupal from Lyceum -- so they get handled the same way, which has to be wrong for one case at least.
