Approving youtube.com

Issue:
Customer installed IWSS 3.1 on Windows 2003 svr. They enabled the URL filtering and block access to Streaming Media / MP3 category. However, they want to approve www.youtube.com.

I have tried to add in youtube* and *youtube* in the approved URL list. But the youtube page doesn't appear correctly. Some of the page elements are missing. What's wrong.

Answer:
Please try to add the following in the HTTP> URL Filtering > Settings > Approve URL List

- Choose URL keyword and enter the following string

ytimg.com
youtube.com

Note: Actual strings shown after adding them is as follows:

*ytimg.com*
* youtube.com*

Please be informed that youtube has to retrieve files from different servers which are hosted under youtube.com and ytimg.com. The thumbnails/pictures are usually stored under ytimg.com while the actual flv files are located on servers under youtube.com. One example is the “v21.lscache2.c.youtube.com”. The retrieval of the files depends on the current location of the browser requesting the site and depends on which server hosts the requested files.
