The main issue is with the Microsoft’s way of implementing Webdav protocol for accessing web content through Microsoft Web Client. When we click on a Office document then web client  sends HTTP /1.1 OPTIONS Request header to server to check the WebDav communication (My server doesn’t have WebDav). In response Apache return 200 OK Response header to Web Client which results in prompting the authentication screen by Windows 7.  Well you have option in IE to pass the authentication login automatically but that would be security breach as you will be exposing your machine authentication to internet so I would not prefer that. Best way is to configure Apache to reject these request. This is how i have solved. These changes needs to be done in httpd.conf file in /etc/httpd/conf folder (Cent OS 4.6)

# One way to doing it – Deny access based on request method

RewriteEngine On

RewriteCond %{REQUEST_METHOD} ^(OPTIONS|PROPFIND)$ [NC]

RewriteRule ^.*$ – [F,L]

# Another way to implementing – Deny acess based on user agent (Vista and Windows 7 used same user agent with different version so this Regx shall work for both

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} ^Microsoft-WebDAV-MiniRedir

RewriteRule ^.*$ – [F,L]

Explanation on Flags:

1. [F] flag causes the server to return a 403 Forbidden status code to the client.

2. Use of the [NC] flag causes the RewriteRule to be matched in a case-insensitive manner. That is, it doesn’t care whether letters appear as upper-case or lower-case in the matched URI.

3. The [L] flag causes mod_rewrite to stop processing the rule set. In most contexts, this means that if the rule matches, no further rules will be processed. This corresponds to the last command in Perl.

Release is available on github https://github.com/rakudo/star/downloads

We have a Delhi.pm Perl Monger Group in New Delhi, India. The group is almost  inactive for some years (except monthly mail of mailing list membership detail). I am trying to revive Delhi.pm and need suggestions from community.

I have already created a Google + page to spread the word. Actually, we have a mailing list but I assume that most of the members are either inactive or not working in Perl anymore.  I know many active Perl programmers in Delhi but they are not connected.

Do let me know your thoughts to make Delhi.pm active? Comments/advice are most welcome.
