amazon web services - AWS CloudFront Behavior -

-

i've been setting aws lambda functions s3 events. want set new structure bucket, it's not possible--so set new bucket way want , migrate old things , send new things there. wanted have of structure same under given base folder name old-bucket/images , new-bucket/images. set cloudfront serve old-bucket/images now, wanted add new-bucket/images well. thought behavior tab set such check new-bucket/images first old-bucket/images. alas, didn't work. if object wasn't found in first, end of line.

am misunderstanding how behaviors work? has attempted this?

that expected behavior. origin tells amazon cloudfront obtain data serve users, based upon prefix, suffix, etc.

for example, serve old-bucket/* 1 amazon s3 bucket, while serving new-bucket/* different bucket.

however, there no capability 'fall-back' different origin if file not found.

you check existence of files before serving link, , provide different link depending upon files stored. otherwise, you'll need put of files in location matches link serving.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
