+Subject: [PATCH 3/5] BUG/MEDIUM: ssl: Fix to not serve expired OCSP responses.
+
+For some browsers (firefox), an expired OCSP Response causes unwanted behavior.
+
+Haproxy stops serving OCSP response if nextupdate date minus
+the supported time skew (#define OCSP_MAX_RESPONSE_TIME_SKEW) is
+in the past.

+Subject: [PATCH 5/5] BUG/MAJOR: session: revert all the crappy client-side
+ timeout changes
+
+This is the 3rd regression caused by the changes below. The latest to
+date was reported by Finn Arne Gangstad. If a server responds with no
+content-length and the client's FIN is never received, either we leak
+the client-side FD or we spin at 100% CPU if timeout client-fin is set.
+
+Enough is enough. The amount of tricks needed to cover these side-effects
+starts to look like used toilet paper stacked over a chocolate cake. I
+don't want to eat that cake anymore!
+
+All this to avoid reporting a server-side timeout when a client stops
+uploading data and haproxy expires faster than the server... A lot of
+"ifs" resulting in a technically valid log that doesn't always please
+users, and whose alternative causes that many issues for all others
+users.
+
+So let's revert this crap merged since 1.5-dev25 :
+ Revert "CLEANUP: http: don't clear CF_READ_NOEXP twice"
+ This reverts commit 1592d1e72a4a2d25a554c299ae95a3e6cad80bf1.
+ Revert "BUG/MEDIUM: http: clear CF_READ_NOEXP when preparing a new transaction"
+ This reverts commit 77d29029af1c44216b190dd7442964b9d8f45257.
+ Revert "BUG/MEDIUM: session: don't clear CF_READ_NOEXP if analysers are not called"
+ This reverts commit 0943757a2144761c60e416b5ed07baa76934f5a4.
+ Revert "BUG/MEDIUM: http: disable server-side expiration until client has sent the body"
+ This reverts commit 3bed5e9337fd6eeab0f0006ebefcbe98ee5c4f9f.
+ Revert "BUG/MEDIUM: http: correctly report request body timeouts"
+ This reverts commit b9edf8fbecc9d1b5c82794735adcc367a80a4ae2.
+ Revert "BUG/MEDIUM: http/session: disable client-side expiration only after body"
+ This reverts commit b1982e27aaff2a92a389a9f1bc847e3bb8fdb4f2.
+
+If a cleaner AND SAFER way to do something equivalent in 1.6-dev, we *might*
+consider backporting it to 1.5, but given the vicious bugs that have surfaced
+since, I doubt it will happen any time soon.
+
+Fortunately, that crap never made it into 1.4 so no backport is needed.
