youtube.com problem (also with videos.google.com)

Hello Aaron,

 

 

Let me thank you in the first place for your reply. User interactivity is indeed the best way to help each other.

 

 

The problem I was facing is already solved. Not by iRule usage because F5 support told me that they do not officially support iRules.

 

 

I couldn't use a source based persistence because behind the link controllers were a cluster of Bluecoat proxies and they were hiding all the user space address.

 

 

I was able to solve the problem by pinpointing the source of it. Somehow the load balancing algorithm was the cause of the problem. It was set to fastest application (I have to read about this method since I don't know how it works) and changed it to least connections.

 

 

As soon as I set the least connections balancing method, the problem was gone.

 

 

Somehow fastest application is incompatible to video.google.com and youtube.com architecture.

 

 

Regarding the iRule, when I tried to insert the following iRule into the Link Controller:

 

when HTTP_REQUEST {

 

if { [findstr [HTTP::uri] contains "85.88.135.19"]} {

 

pool Router_COLT

 

} elseif { [findstr [HTTP::uri] contains "213.58.138.182"]} {

 

pool Router_ONI

 

}

 

}

 

 

It came out with the following error messages:

 

 

01070151:3: Rule [youtube_persist] error:

 

line 1: [ltm_rule_L7 feature not licensed] [when HTTP_REQUEST {

 

if { [findstr [HTTP::uri] contains "85.88.135.19"]} {

 

pool Router_COLT

 

} elseif { [findstr [HTTP::uri] contains "213.58.138.182"]} {

 

pool Router_ONI

 

}

 

}]

 

line 2: [ltm_rule_L7 feature not licensed] [HTTP::uri]

 

line 2: [invalid integer] ["85.88.135.19"]

 

line 4: [ltm_rule_L7 feature not licensed] [HTTP::uri]

 

line 4: [invalid integer] ["213.58.138.182"]

 

 

It was at this time that I abandoned the iRule solution when F5 support told me they weren't supporting iRules.

 

 

Best regards,
