NimbostratusHow to remove Cache-Control from the header
Hi,
we wanted to remove the Cache-Control from HTTP Response.
using below code but does not work.
I can still see a Status code as 200.
if { [HTTP::uri] == "/.img" } {
set remove_cache_control_header 1
}
when HTTP_RESPONSE {
if { $remove_cache_control_header == 1 and [HTTP::header exists Cache-Control] } {
HTTP::header remove "Cache-Control"
}
}
Can you please suggest
L4L7_53191Puli: could you paste a header dump of this traffic? I would add some logging to the HTTP_RESPONSE event to log the value of Cache-Control before you scrub it. Then confirm your browser doesn't see this header.
A 200 response isn't a valid indicator of whether or not this header was removed, so it's best to look at the HTTP headers to be sure.

In addition to Matt's helpful suggestions, you might double check the URI you're looking for in the HTTP_REQUEST event. Did you just put /.img to anonymize the iRule or is that what you're using?
