c# - Integrating FormsAuthentication from asp.net in classic asp -

recently have been tasked creating single sign on between 2 web sites, wuth different domains. 1 runs under asp.net , other under classic asp. since have little experience asp.net (i'm java enthusiast) , 0 experience in asp (plus dated , hate that), i'm encountering lot of difficulties. first 1 being: how pass authentication cookie coming asp.net web asp web?

i found article, wich seems describe need:

http://www.santry.com/blog/tabid/90/id/1156/creating-a-single-sign-on-for-aspnet-application-and-legacy-asp-application-part-ii.aspx

but problem assumes lot of previous knowledge on web development tools uses (for instance, com interoperability wrappers, api's , such ), , it's getting hard figure out of it. however, core idea of extracting formsauthentication utilities , using them in legacy asp.

so need guideline achieve described in link above in order create @ least functional test (with functional meaning can send credentials in cookie dummy asp.net web , receive cookie in classic asp form), or alternative method implement single sign on between these 2 sites.

one important thing note cannot via wildcard mappings because have no access iis configuration.

you never able send authentication cookies received 1 domain web site on domain. browsers same origin policy prevent this.

to make work, want single sign on (sso) solution both web applications authentication cookies same security token service (sts).

this easy asp.net. system.identitymodel namespace. have no clue if available classic asp.

good luck.
