[infinispan-issues] [JBoss JIRA] Commented: (ISPN-858) MIMECacheEntry requires a version

[Manik Surtani (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12573264#comment-12573264 ] 

Manik Surtani commented on ISPN-858:
------------------------------------

Right, timestamps are poor for this anyway.

http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.11

calcETag() is incorrect.  

https://github.com/infinispan/infinispan/blob/master/server/rest/src/main/scala/org/infinispan/rest/Server.scala#L129

Perhaps an incremental (atomic) counter?  But that may cause unnecessary HTTP cache invalidation.  SHA hash on the byte[] contents of the MIMEEntry?  Maybe reuse the MurmurHash impl in org.infinispan.util.hash ?

> ETag calculation requires MIMECacheEntry to carry a version similar to HotRod/Memcached in order to avoid collisions with closely followed updates.
