Safari on IOS 5 randomly switches images
Ofcourse we believe its a bug in ios, but we havent been able to replicate the problem when skipping bigip and sending the http traffic straight to the varnish servers.
Please read our blog for details: http://tech.vg.no/2011/12/14/safari-on-ios-5-randomly-switches-images/
Has anyone else seen anything similar?

- hooleylistCirrostratusHi Stein,
- peloquin_71298Historic F5 AccountHey Stein -
- stein_87754NimbostratusHi,
we're using ltm v 10.2.2-763.0
tmsh list ltm virtual touch.vg.no
This one gives no swapped images:
ltm virtual touch.vg.no {
destination 195.88.55.71:http
ip-protocol tcp
mask 255.255.255.255
persist {
source_addr {
default yes
}
}
pool varnish_m323_l4
profiles {
fastL4 { }
}
snat automap
}
But this one does:
ltm virtual vg.no_m323 {
destination 195.88.55.16:http
ip-protocol tcp
mask 255.255.255.255
pool varnish_m323
profiles {
tcp-lan-optimized {
context serverside
}
tcp-wan-optimized {
context clientside
}
}
rules {
selectively_disable_snat
add_cookie_a55
add_X-VG-ClientInfo
}
snatpool m323_www.vg.no_snatpool
}
- hooleylistCirrostratusCan you try the L7 virtual server with a custom OneConnect profile with a /32 source mask?
- stein_87754NimbostratusThat could be a problem, as OneConnect and Varnish is not the best of friends. Havent tried it in a few years, but the last time I tried OneConnect, Varnish closes the connection before the BigIP wants it to, resulting in 200OK, but empty responses to the client.
