i have service returns same results given parameter. naturally cache results on client. is there way introduce caching , other effect inside wcf pipeline? perhaps custom binding class site between client , actual http binding. edit: just clear, i'm not talking http caching. endpoint may not http , looking @ far more effects caching. example, 1 effect need prevent multiple calls same parameters. the wcf service can use cache-control directives in http header client how should use client side cache. there many options, the part of http protocol . can example define how long client can data local cache instead of making requests server. clients implemented http, web browsers, follow instructions. if client use ajax requests wcf server, corresponding ajax call return data local cache. moreover 1 can implement many interesting caching scenarios. example if 1 set "cache-control" "max-age=0" (see here example), client make revalidation of ca...

can enumerate exposing myself (and site) running/deploying grails app "grails run-app" rather doing "correctly" .war file? grails.org saysl grails should never deployed using grails run-app command sets grails in "development" mode has additional overheads. is only performance, or there security issue there too? performance big difference. if must use run-app sure run 'grails prod run-app' @ least of optimizations in place. run-app designed devloper-friendly, lots of reloading, , corresponding file system scans necessary support that. when running in war, gsps precompiled, saves permgen , results in faster performance. there's no caching in run-app since developer don't want have restart, in production need make changes redeployment, caching more aggressive.
