c# - Retrieve external html file and securely display in browser -

i working on online publication subscription site. developed in asp.net mvc 1.

basically, user purchases magazine or newspaper , path publication becomes available them. however, catch 22 is, not allowed see filepath publication unsecured.

i've built function can retrieve publication , download without showing filepath user problem because publication html file needs other files , folders in same directory view magazine or newspaper.

i know might download entire directory folder, unreasonable can 200mb. thought maybe retrieving filepath , redirecting page load publication in iframe think security risk bit of knowledge of browsers can view source , filepath there.

if has suggestion of secure way retrieve html file , display in browser, appreciated. thanks.

easy! store secret urls in database table, , reference them id instead.

set new controller action follows:

public contentresult shownewspaper(long id) {     var mysecreturl = db.secreturls.where(k=>k.id == id).firstordefault(); // grab url entry database     string htmlcode = "";     if(mysecreturl != null) {          webclient client = new webclient();          htmlcode = client.downloadstring(mysecreturl.url);     }else{          htmlcode = "page not found!";     }     return content(htmlcode,"text/html"); } 

so if call:

mysite.com/home/shownewspaper/5 

this load html @ url stored in database record 5

you go step further , check see whether or not controller action called site (as opposed directly) checking referrer.

hope helps...

edit: store "authorised user id" in database record too, , check accessible if id matches logged in user id, prevent unauthorised access controller action , therefore magazine... if not, redirect them login screen

return redirect("/myloginurl");
