You can't even serialize a CFC with WDDX, but they will happily live in the session scope. If you do use client scope make sure you abstract it with a good layer around it so that what scope you use is transparent to your application so that you can change it in the future without your application noticing. Look to the Facade design pattern for that.

Allen made a good point about WDDX. I tend to overlook CFWDDX.
<cfwddx action = "" input = "#session#" output="client.foo">
<cfdump var="#client.foo#"> can dump your session into foo variable stored into the client scope.
Your result in the DB would look similar to:
foo=<wddxPacket version#='1.0'><header/><data><struct type#=' coldfusion.runtime.MemorySessionScope'><var name#='cftoken'><string>88107569</string></var><var name#='urltoken'><string>CFID#=7101&CFTOKEN#=88107569</string></var><var name#='cfid'><string>7101</string></var><var name#='sessionid'><string>TESTAPP_7101_88107569</string></var></struct></data></wddxPacket>#

Also, if you do this and you have your client variables stored in the database, you'll want to make sure your datasource is enabled to retrieve BLOB's without the 64k limit.One other thing, if you're running on MX in JRUN configuration (not standalone), you can share the sessions between servers (if I remember right). J2EE has clustering built in and I believe it supports the equivalent of a session state server.Allen-----Original Message-----

Subject: Re: Re: [ACFUG Discuss] Client? Session?
In general it seems to me that the rule is that once a user is on a server, they are on the same server. Define complex data. I potentially see structures and possibly an occasional object in the shared scope, but honestly I don't know yet. We don't officially have any code written.

Yeah it depends on how you want your requests routed... it is my
understanding that if you want the machines to round robin each
request then you need to do client variables, if you don't care and
you just want users to stay on one server then you can use sessions.
