Coherence*Web      

  •  HTTP  session-­‐management  module  (built-­‐in  feature  of  Coherence)  

•  Supports  wide  range  of  applicaaon  servers  •  Does  not  require  any  changes  to  the  applicaaon  •  Allows  session  state  to  be  managed  in  the  various  

caching  topologies  •  Allows  storage  of  session  data  outside  of  Java  EE  

applicaaon  server  •  Heterogeneous  applicaaons  running  on  mixed  

hardware/OS/applicaaon  servers  can  share  common  user  session  data.

Coherence*Web  is  easy  to  use      

 •   Modify  web.xml  and  weblogic.xml  

•   Deploy  coherence-­‐web-­‐spi.war  

•   Configure  Coherence  Cluster  

Use  Coherence*Web  When      

 • You  don’t  want  to  loose  sessions  while  restarang/maintaining  your  applicaaon  

• Your  applicaaon  works  with  large  HTTP  session  state  objects  

• You  run  into  memory  constraints,  due  to  storing  HTTP  session  object  data  

• You  want  to  off-­‐load  HTTP  session  storage  to  an  exisang  Coherence  cluster  

• You  want  to  share  session  state  across  EAR  files  and  applicaaon  servers
