<p>How do you compress Script Resources of ASP.Net? I saw a file there reached up to 255 KB! I tried finding solutions, but so far it only talks about scripting dynamic and static files. I checked the compression temp folder of IIS and found no compressed scripted resource there. That led me to the conclusion that these files are transferred over with high bandwidth.</p>
