How does ASP. NET implement static pages? First, let's look at the source code example of ASP. NET:

 
 
    
  
  
  1. <! -- Main. Aspx -->
    2. 
  
  
  2. <%@ Page language ="C #"%>
    3. 
  
  
  3. <%@ ImportNamespace= System. IO %>
    4. 
  
  
  4. <Script runat ="Server">
    5. 
  
  
  5. ProtectedOverrideVoidOnInit (EventArgs e)
    6. 
  
  
  6. {
    7. 
  
  
  7. IntId;
    8. 
  
  
  8. Try
    9. 
  
  
  9. {
    10. 
  
  
  10. Id =Int. Parse (Request. QueryString ["Id"]);
    11. 
  
  
  11. }
    12. 
  
  
  12. Catch
    13. 
  
  
  13. {
    14. 
  
  
  14. Throw(NewException ("No id specified for the page"));
    15. 
  
  
  15. }
    16. 
  
  
  16. 
  
  
  17. String filename = Server. MapPath ("Statichtml _"+ Id +". Html");
    18. 
  
  
  18. 
  
  
  19. // Try to read an existing file 
    20. 
  
  
  20. Stream s = GetFileStream (filename );
    21. 
  
  
  21. If(S! = Null)// If the file exists and is read successfully 
    22. 
  
  
  22. {
    23. 
  
  
  23. Using(S)
    24. 
  
  
  24. {
    25. 
  
  
  25. Stream2Stream (s, Response. OutputStream );
    26. 
  
  
  26. Response. End ();
    27. 
  
  
  27. }
    28. 
  
  
  28. }
    29. 
  
  
  29. 
  
  
  30.

    32. 
  
  
  32. StringWriter sw =NewStringWriter ();
    33. 
  
  
  33. Server. Execute ("Main_Execute.aspx", Sw );
    34. 
  
  
  34. 
  
  
  35. String content = sw. ToString ();
    36. 
  
  
  36. 
  
  
  37. // Output to the client 
    38. 
  
  
  38. Response. Write (content );

The principle of implementing static pages in ASP. NET is as follows.

Main_Execute.aspx is the HTML page generated.

Now we use Main. aspx to cache it.

ASP. NET implements the static page process as follows:

First, calculate the file name based on the page parameters. (This example is based on Request. QueryString ["id)

Try to read the cached file. If successful, then Response. End ();

If not:

Use Server. Execute to call Main_Execute.aspx and obtain its results.

After the content is obtained, it is immediately output to the client.

Finally, write the content into the file and provide it to the next cache.
