iRule cannot fetch iFile (wpad.dat)

Hi AMG and F5_Rock. Thanks for your support. I have checked the iFile exist and the Iruel scan be saved after validating the file path so it could be iFile content is not correct. Below is the brief content of wpad.dat file. Do you see any invalid parameters which could cause fetching issue?

function FindProxyForURL(url, host) {

// Send via proxy if (shExpMatch(url, "http://news.com.au/") || shExpMatch(host,"optus.com.au") ) return "PROXY webproxy.test-domain.com:8080";

// Send direct if (shExpMatch(host,".yahoo.com") || shExpMatch(host,".telstra.com") || shExpMatch(host,"*.weather.com.au") ) return "DIRECT";

// DEFAULT RULE: All other requests, send via proxy return "PROXY webproxy.test-domain.com:8080"; }

regards, Rob

Should be no issue with the iFile as simply plain text.

Is the iFile and the Virtual Server you are assigning the iRule to in the same partition, i.e. both in partition named 'MDD'?

If you try the following, removing the partition reference:

when HTTP_REQUEST {
  switch -glob [string tolower [HTTP:uri]] {
    "/mdd/wpad.dat" {
      HTTP::respond 200 contain [ifile get wpad.dat] "Content-Type" "application/x-ns-proxy-autoconfig" "pragma" "no-cache"
    }
    default {
      HTTP::respond 404 content "You've asked for something we don't have."
    }  
  }
}

Failing this can you run the folllowing and share the output:

tmsh list sys file ifile /MDD/wpad.dat
tmsh list ltm ifile /MDD/wpad.dat

I managed to fix the issue by changing iRule. Line 2-3 do not work so I replace them with simple "if { [HTTP::uri] starts_with "/wpad.dat" then client can fetch wpad file and browse properly now. Thanks AMG and F5_rock for your willingness to assist me.
