[jira] [Updated] (TS-844) ReadFromWriter fail in CacheRead.cc

Attachment: TS-844-2.patch

@John Plevyak
This problem is hard to reproduce now, but i think the reason is because: when 
a write has been closed normally, something wrong happens to create a invalid 
HttpInfo, leading to fail ink_assert(w-alternate.valid()); in 
CacheVC::openReadChooseWriter, and ts crash.   In my patch, i just prevent this 
happen, maybe the better way is like this, see TS-844-2.patch, or just remove 
that ink_assert line, because follow it is a if condition judgment.

(was: @John Plevyak
This problem is hard to reproduce now, but i think the reason is because: when 
a write has been closed normally, something wrong happens to create a invalid 
HttpInfo, leading to fail ink_assert(w-alternate.valid()); in 
CacheVC::openReadChooseWriter, and ts crash.   In my patch, i just prevent this 
happen, maybe the better way is like this, see TS-844-2.patch, or just remove 
that ink_assert line, because follow it is a if condition judgment.)
