how to make seperate DLLs for .aspx having same name

I have two folders having same named files in them eg;

wiki/default.aspx
study/default.aspx

The problem is when i pre-compile this app it generates dll for both these file but with same name as...

App_Web_default.aspx.bf94b8ff.dll
App_Web_default.aspx.cdcab7d2.dll

Now the Question is how will I differenciate that which dll is of which .aspx page? Which one is wiki/default.aspx's dll and which on is App_Web_default.aspx.cdcab7d2.dll's dll
