Serving wpad.dat with F5?

 

 

With the rule which doesn't check the host or URI (Click here), all requests to the VIP will be answered with the contents:

 

 

function FindProxyForURL(url, host) {

 

if(shExpMatch(host, "*[^0123456789.]*") == false)

 

if( isInNet\(host, "127.0.0.0", "255.0.0.0")

 

|| isInNet(host, "172.17.0.0", "255.255.0.0")

 

|| isInNet(host, "172.18.0.0", "255.255.0.0")

 

)

 

return "DIRECT"; \

 

else

 

return "PROXY proxygateway.internal:8080; DIRECT";}

 

 

Do you want to send the same response content for every request? If so, you can use the linked iRule and you don't need to check the requested host header or URI.

 

 

If you do want to send a different response based on either the requested host or URI, then you could use a switch statement or a datagroup with the matchclass command to check the requested host and/or URI.

 

 

Can you clarify what you need to implement?

 

 

 

 

Yes, this is good rule, but I'd like just avoid clients to write in their browsers config anyhing more or less, then just /wpad.dat or /cache.pac in the end, as maybe after some time proxy's will hold the wpad.dat file and then will be troubles, if clients did make some typo in name, as with this iRule it does't matter what there is at all.

 

 

 

So swith without hostcheck?
