FF performance issues after HttpOnly flag appended to cookies

Hi all, I am experiencing issues with firefox (IE runs fine) when I added this iRule to VIP (shared VIP for about 20 domains, iRule choosing appropriate pool is used):

 

This iRule adds "httponly" flag at the end of each cookie in HTTP responses (applied only for one domain) and iRule works fine.

 

 

when HTTP_REQUEST {

 

 

set domaincalled 0

 

 

if { [HTTP::host] contains "xxxxxx.com" } {

 

set domaincalled 1

 

}

 

}

 

 

when HTTP_RESPONSE {

 

 

if { $domaincalled equals 1 } {

 

set ck [HTTP::header values "Set-Cookie"]

 

HTTP::header remove "Set-Cookie"

 

 

foreach acookie $ck {

 

HTTP::header insert "Set-Cookie" "${acookie}; HttpOnly"

 

}

 

}

 

}

 

 

Do you know why it causes slowness (page loading ~10 seconds) and why its only noticed via firefox?

 

 

Thanks a lot,

 

Zdenek

    There's no apparent reason for this. As this is a browser specific issue I'd suggest you use a tool like LiveHTTPHeaders to check what is actually being seen in the HTTP headers in FF. Beyond that, a Wireshark packet capture on the client would also be useful in troubleshooting your issue.

    Hi,

     

    thanks for message, performance issues weren't caused by this iRule but by another device.
