first of i'm sorry if question belong, if please let me know should post if possible. i have discovered esi , hinclude ways boost side performance, have searched , down , not find document on how search engines index pages using these. think since hinclude use javascript not possible search engines index content included dynamically them. i'm not sure esi, content indexed or left out well? hope can shed light on me on topic. regards esi processed "edge-side" - example akamai or varnish. client never sees esi include tags, see rendered page. hinclude processes client-side means search engine's spider need able process javascript. search engines seem moving direction may not support it.

i have local.properties file in git repo android project. on build server checking out git , running gradle targets execute unit tests. build server linux , i'm on mac android sdk installed different, change don't want to. does android_home override local.properties; can't tell if i'm setting environment variable correctly in jenkins (build server) or if local.properties beats env variable. source i've been reading is: http://tools.android.com/tech-docs/new-build-system/user-guide note: need local.properties file set location of sdk in same way existing sdk requires, using sdk.dir property. alternatively, can set environment variable called android_home. on tools i've seen, local configuration override environment variables. from jenkins perspective, using environment variables makes sense can propagated multiple projects.
