Basically my problem is with rewriting a Citrix Web interface url on a IIS v6 server using isapi v3(lite).   Previous to this I was using v2(lite) on IISv5 with no problem.

In previous IISv5 server, which had only one website configured and no additional headers defined for the website other than the default, I was using isapi v2 with httd.ini as follows:

--------------------------

[ISAPI_Rewrite]

# Defend your computer from some worm attacks
RewriteRule .*(?:global.asa|default\.ida|root\.exe|\.\.).* . [F,I,O]

# Citrix Login page
RewriteCond Host: (CitrixApps\.mycompany\.com)
RewriteRule / /Citrix/MetaFrame/auth/login\.aspx [L,I]

--------------------------

This config worked as expected with url http://citrixapps.mycompany.com being rewritten to http://citirix.mycompany.com/citrix/metafram/auth/login.aspx (there is a dns entry in our domain that points this the host even though there is no IIS header defined on website for citrixapps)

Now I want http://citrixapps.mycompany.com, (dns changed to point to new server) to be rewritten on new IIS v6 server using isapi v3(lite) to http://citrixapps/citrix/accessplatform/auth/login.aspx.

I sort of have it working, but with erratic results.  Not sure what I am doing woring or if I need to buy full version.  Here are my details.

On this IIS v6 server I have multiple websites defined with dedicated ip addresses configured for each site.  In the site in which I installed the Citrix Web Interface I had to create additional site headers (without it I was just getting page can not be displayed), I added to headers citrixapps, and citrixapps.mycompany.com.  So, as I stated above, I want http://citrixapps.mycompany.com, which now points to my new website, on new server, to be rewritten to  http://citrixapps/citrix/accessplatform/auth/login.aspx.

When I use a httpd.conf file like the following:

--------------------------

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.56

RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
RewriteLogLevel 9
#RewriteBase /
# unsupported directive: [ISAPI_Rewrite]

#  Defend your computer from some worm attacks
RewriteRule ^.*(?:global.asa|default\.ida|root\.exe|\.\.).*$ . [NC,F,O]

##  Citrix Login page

RewriteCond %{HTTP:Host} ^(citrixapps\.mycompany\.com)$
RewriteRule ^/$ /Citrix/accessplatform/auth/login\.aspx [NC,L]

RewriteCond %{HTTP:Host} ^(citrixapps)$
RewriteRule ^/$ /Citrix/accessplatform/auth/login\.aspx [NC,L]

--------------------------

I get 403 message " You are not authorized to view this page."  In the address bar I just see http://citrixapps/.

My thoughts are that this particular problem has something to do with IIS permissions on the directory how it uses the different accounts(aspnet, network service) to serve the page.  If I disable the rules and use the url http://citrixapps/citrix/accessplatform/auth/login.aspx directly I have no problem.  So I don't really understand why using the rewrite would deny me permission to the page, when not using rewrite and using the full url directly works fine.
Permissions on the application directory root are Administrators(full), Authenticated users(RX), Network Service(RX).  I don't know if not having the aspnet account in the permisisons is causing the problem, but it works without out trying to rewrite, so before I make any changes to permission I want to see if I am doing rewrite correclty.
Here is excerpt from rewrite.log

--------------------------

If I use the following httpd.conf file to try and redirect to the new url I get strange results

--------------------------
# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.56

RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
LogLevel debug
RewriteLogLevel 9
#RewriteBase /
# unsupported directive: [ISAPI_Rewrite]

#  Defend your computer from some worm attacks
RewriteRule ^.*(?:global.asa|default\.ida|root\.exe|\.\.).*$ . [NC,F,O]

##  Citrix Login page

RewriteCond %{HTTP:Host} ^(citrixapps\.mycompany\.com)$
RewriteRule (.+) http://citrixapps/citrix/accessplatform/auth/login\.aspx$1 [L,I,R]

--------------------------

This seams to  works fine and I could live with it, but the logs does not make it look like it worked cleanly.  any idea of what is going on before the actually redirection occurs?

--------------------------

It just goes on and on and on until I stop the browser.   If I use this next httpd.conf file, I get the same as above for both http://citirxapps and http://citrixapps.mycompany.com.

--------------------------

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.56

RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
LogLevel debug
RewriteLogLevel 9
#RewriteBase /
# unsupported directive: [ISAPI_Rewrite]

#  Defend your computer from some worm attacks
RewriteRule ^.*(?:global.asa|default\.ida|root\.exe|\.\.).*$ . [NC,F,O]

##  Citrix Login page

RewriteCond %{HTTP:Host} ^(citrixapps)$
RewriteRule (.+) http://citrixapps/citrix/accessplatform/auth/login\.aspx [L,I,R]

RewriteCond %{HTTP:Host} ^(citrixapps\.mycompany\.com)$
RewriteRule (.+) http://citrixapps/citrix/accessplatform/auth/login\.aspx [L,I,R]

--------------------------

Any help on getting this working would be appreciated.

Anton, Worked like a charm.

For my information, can you explain a bit.

For instance the first rewrite condition, and needing to use "r=301".

Thanks again I really appreciate it.
