How to flush Cache using Curl Command in Adobe CQ/AEM

Use Case Flush cache for a path in regular interval of time

Solution You can use the following command to flush cache


curl -H "CQ-Action:Flush" -H "CQ-Handle: /content/geometrixx/en/toolbar" -H "CQ-Path:/content/geometrixx/en/toolbar" -H "Content-Length: 0" -H "Content-Type: application/octet-stream" http://dispatcher-server-hostname:port/dispatcher/invalidate.cache

In the Newer version of dispatcher try this

curl -H "CQ-Action: DELETE" -H "CQ-Handle:/content/geometrixx/en/toolbar" -H "CQ-Path:/content/geometrixx/en/toolbar" -H "Content-Length: 0" -H "Content-Type: application/octet-stream" http://dispatcher-server-hostname:port/dispatcher/invalidate.cache

Expected Response: <H1>OK</H1>
If you see error like
[Thu May 30 09:23:53 2013] [D] [91650(140735211479424)] Found farm <Your FARM>
[Thu May 30 09:23:53 2013] [D] [91650(140735211479424)] checking [/dispatcher/invalidate.cache]
[Thu May 30 09:23:53 2013] [W] [91650(140735211479424)] Flushing rejected from <Something>
That mean you are not in allowed list of client to flush cache. In that case please allow your IP (<SOMETHING>) in above case in allowedClient section of dispatcher.any

/allowedClients
{
/0000
{
/glob "*"
/type "deny"
}
/0001
{
/glob "<Something>"
/type "allow"
}
... More allowed
}
}

Important Note: Make sure that from outside (DMZ may be) no one should be able to run this command. This command should be allowed to run only from some trusted boxes
