red5 - Solution for handling Spring security session Id in different wed apps -

-

i have 2 web application on different wed servers: core (spring 3.0.5, spring security 3.0.5, postgresql) , red5

i need develop next workflow:

  1. user logins in core
  2. system returns web page simple html , flex app
  3. user streams audio on red5 flex app
  4. red5 uses core check if user logged in
  5. red5 sends file core
  6. core identifies file come appropriate user
  7. core stores file in related user's folder

i have configured spring security @ core, flex client streams audio red5, servlet on red5 stores audio in flv file , have access file.

my idea is:

  1. in case of successful login core returns sessionid
  2. at end of recording flex app sends sessionid red5 server
  3. red5: makes http request sessionid core
  4. core returns "true" in case of user logged in
  5. red5: makes http post request 2 parameters: file , sessionid
  6. core identifies user , stores file in user's folder

please provide mechanism how sessionid, how check if user logged in , how user sessionid or better approach implement described workflow

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
