[plt-scheme] Web-server and servlet

Hello,

Thank you for all of your suggestions last time. 

Now I have read the documents about the Web-server and servlet and can write 
some simple servlets. But I still have two problems: 

1 

In the Help-Desk -- Documentation for the web-server collection, there is 
one topic "Developing Servlets", which says "require the module servlet 
development library.  (require (lib "develop-servlet.ss"))".  Doing so  
raise the error : open-input-file: cannot open input file: "C:\Program 
Files\plt\collects\mzlib\develop-servlet.ss". I searched my hard disk and 
still can't find a file with name"develop-servlet". 

2

Using send/suspend, I can get a single input from a Web form. But how to 
handle several inputs from a Web form? For example, the add.ss example in 
DrScheme use two web page to get the two numbers to add. How two get them 
in one form?
