Rewriting of HTTP Headers
Hi everybody.
I'm new in this community and it could be possible that this issue has been already treated.
I'm having a problem with my WA 4500. If I access directly to my origin servers, I get the following HTTP-HEADER
Expires: Thu, 22 May 2008 21:55:53 GMT
Cache-Control: public, max-age=3600
But when I pass thru my WAs the header changes into:
Expires: Thu, 22 May 2008 21:55:53 GMT
Cache-Control: private, max-age=3600
As the support guys told me, this is a bug of the product that seems to REWRITE HTTP-HEADERS.
In order to solve that situation I've tried with some iRules but without success
The idea is to rewrite the headers when I detect that the http-header directive is equal to "private, max-age=3600" into "public, max-age=3600"
But I need also to restrict this operation to those files that end with ".html"
I've tried with this iRule, but it is incorrect because [HTTP::uri] is not a clause of the HTTP_RESPONSE method :
when HTTP_RESPONSE {
if {([HTTP::header Cache-Control] eq "private, max-age=3600") and ([HTTP::uri] ends_with “.html”)} {
HTTP::header replace Cache-Control "public, max-age=3600"
}
}
Any suggestion?
Regards
Federico
