Block domain exept one URL of the domain

Marco, please insert a picture of the solution that didn't work and show the line from the Web Filtering log where you got the wrong result.

Correct regex syntax would be:
^https?://([A-Za-z0-9.-]*\.)?example\.com/weneedthislink

Hello Bob

We want to block youtube due to low bandwith. But the users should be able to watch just one youtube-movie. The movie used here is just an example.

The exact Regex i inserted for testing purposes in "block these website" is: ^https?:\/\/([A-Za-z0-9.-]*\.)?youtube\.com(?!\/watch\?v=qmdBfsOkeEI)

I tested the Regex on different Regex-Testing sites and it looks ok. youtube.com results in a match but https://www.youtube.com/watch?v=qmdBfsOkeEI doesn't match.

When I call the site www.youtube.com/watch the Sophos Web Proxy shows the following:

The Sophos log tells the following:

2016:04:06-16:30:37 xxxx httpproxy[9911]: id="0062" severity="info" sys="SecureWeb" sub="http" name="web request blocked, forbidden url detected" action="block" method="CONNECT" srcip="xxx" dstip="" user="xxxx" ad_domain="xxxx" statuscode="403" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2951" request="0xe020f000" url="https://www.youtube.com/" referer="" error="" authtime="46" dnstime="0" cattime="111" avscantime="0" fullreqtime="208082" device="0" auth="2" ua="Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko" exceptions=""

Thanks and regards,

You will have to block Youtube on the global level and to create filtering exception like this:

^https?://([A-Za-z0-9.-]*\.)?ytimg\.com/
^https?://([A-Za-z0-9.-]*\.)?googlevideo\.com/
^https?://([A-Za-z0-9.-]*\.)?ggpht\.com/

And also regex for every single video, like:
^https?://([A-Za-z0-9.-]*\.)?www\.youtube\.com/watch\?v=37b4KkJDEDs

Tested successfully on firmware version 9.313 last summer at a client site while doing PoC (Proof of Concept) demonstration.

How to completely block Youtube using tag:

Hello Vilic

Thank you very much for your explanation. I tried but it doesn’t work…sometimes I start doubting on me…

What I tried:

WebProtection/WebFilterProfiles/FilterActions/DefaultContentFilterAction/Websites/BlockTheseWebsites:

Regex = ^https?://([A-Za-z0-9.-]*\.)?youtube\.com/

This blocks youtube successfully!

Then I made an exception in WebProtection/FilteringOptions/Exceptions:

Regex =  ^https?://([A-Za-z0-9.-]*\.)?www\.youtube\.com/watch\?v=37b4KkJDEDs

 When I enter now the URL = https://www.youtube.com/watch?v=37b4KkJDEDs in the browser I still get a blocked page:

For troubleshooting I entered “https?://([A-Za-z0-9.-]*\.)?www\.youtube\.com/watch\?v=37b4KkJDEDs” in WebProtection/WebFilterProfiles/FilterActions/DefaultContentFilterAction/Websites/BlockTheseWebsites and expected that the URL = https://www.youtube.com/watch?v=37b4KkJDEDs will be blocked:

But it isn’t – the movie can still be watched. What goes wrong?

I use firmware version 9.355-1

Thanks,

Marco

Marco, a picture is worth a 1000 words - please show us your rule and Exception instead of explaining.
