asp.net - SAAS based mobile application -

-

we developing saas based mobile application in asp.net.

in our business domain have different companies , flows under those. each company has different url, when super admin create company on front end , parse url load each company specific logos , other settings.

we confused url management different companies. how should handle different sub domain urls hitting same physical location? , please share other guidelines must follow develop saas based web site.

identifying tenants url standard in developing saas applications.

it pretty easy , straight forward too. experience, suggest following

  1. configure iis site use root level domain (i.e. yourawesomeapp.com). makes subdomain request hit same site.
  2. store tenants url tenant1.yourawesomeapp.com, tenant2.yourawesomeapp.com, etc., in tenant table
  3. tell tenant use url access application
  4. write httpmodule, in postauthenticaterequest event grab current request url , verify tenanturlmapping entries (cache url <-> tenant mapping in dictionary @ application start improve performance)
    • if request domain not in tenanturlmapping; deny access
    • if request authenticated, verify authenticated tenant url/id sames current one, else deny access (tenant url/id can stored in cookie in encrypted format when logon)
    • load required settings , store them in httpcontext.items use in later part of request.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
