Should the Content Engine work while the Inernet link is down ?

[m.abdallah]

I have installed CE590 in a client network

The http saving performance is from 30 : 40 %

My client want to make sure the CE is caching the web site

He want to shutdown Serial port of the main router , and try to browse web sites. ( the Cached sites )

Should he get a reply from the CE and browse the cached sites ??

I mean , Can the PC browser ( while the internet is link is down ) open page like www.yahoo.com for example if it is cached on the CE ??

Is there is any command of the CE that can display the name of the cahced web pages ?

Note : Cisco Content Engine Software Release 3.11

Can anyone help me ?

Thanks

Mohamed,

Before you go any futher you need to upgrade the CE to ACNS 4.2.3. There are known issues with 3.1.1.

To answer your question the CE will only server content if it can not access the internet if the object is fresh. By this I mean the object has not expired or the object does not need revalidation eg If modified since request.

This could cause problems with broken pages etc etc.

Your best option is to turn on transaction logging.

transaction-logs enable

You can then go to the local1/logs directory on the CE

type working.log

This will show you the urls that clients are requesting and if they got a hit / miss/ ims hit / ims miss etc etc.

Overall your cache should always have access to the origin server for content.

Cheers

Phil,

Thanks for your reply

I will upgrade the CE to ACNS 4.2.3 as you recommended

but should I add any changes to configuration after the upgrade ?

Another questions :

If the object is fresh ( the object has not expired ), and the internet link is down , Should the PC browser get the web page from the CE ??? OR the CE should have access to the origin server all the time and PC browser will not get anything Cause the inetrnet is down ???

Is there is any setting in the IE browser ?

Thanks
