Dear All,

I my application I'm checking the size of file in server side(servlet) So when i upload file (above 20mb) Its Taking too time to parse the request in server side.As i'm using appache API to parse the request ,and i also tried in browser side using java scripts but it's not compatible with Mozilla and other browsers please can any body tell me the solution to over come .so that when i upload more than the limit it should alert me

If you are asking how to check the file size on the client, that's not going to happen. Security concerns prevent client code from knowing anything about the file system.

So can i use ajax or Applet to check the file size..?

[Bear Bibeault]

How on Earth would Ajax help?

You might be able to use an Applet -- but the user will have to accept letting the applet check the file system. There's no guarantee that they'll say yes.

Is it possible improve the parsing request performance in server side

On the server side, can't you just check the content-length header and refuse the connection if the size is too large?

I believe the Apache file upload product provides something which allows you to do that. I don't have the documentation handy but it shouldn't be too hard to look it up for somebody who does have the documentation.

I had used the request.getContentType() in my condition to check the file size it will take < 1 sec now to give me the content length but when i redirecting it it ll take 5 min to redirect

 

if(request.getContentType()>15000000)
{
response.sendRedirect("../failure.jsp");
}
else
{
...
   continue the logic to upload..
...
}

[Mark E Hansen]

Can you please check the API and see what request.getContentType() returns?

Is it giving you what you expect?

[santhosh.R gowda]

Sorry for the previous code

 



 if(request.getContentLength()>15000000)  
 {  
 response.sendRedirect("../failure.jsp");  
 }  
 else  
 {  
 ...
   continue the logic to upload..  
 ...  
 }

Please can any body tell me why redirecting taking too much of time to redirect
