bypassStaticCache Issue




6 December 2011 at 2:38am Community Member, 3 Posts


I am using Silverstripe and I found a strange behavior with bypassStaticCache cookie.

I don't know the meaning of this cookie but from my analysis, I realized that the SS is deleting the cookie, even when the browser does not send it. On other hand, the Set-Cookie operation is done twice in the same response.

HTTP request

GET http://localhost/mySite/ HTTP/1.1
Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2

As you can see in response headers, there are 2 Set-Cookie instructions with the same value and current date. The referenced cookie was not send previously by the browser.

Is this a known issue? Anyone know a work around?
