HI All,

An Issue is ​report​ed in production with ajax​ request execution in our application with IE9 browser.

Below is the text from fiddler response raw view for failed ajax request at customer site

ReadResponse() failed: The server did not return a complete response for this request. Server returned 0 bytes.

Could not able to replicate in development environment.

below is the fiddler report for failed ajax request at customer site

== WININET CACHE INFO ============
This URL is not present in the WinINET cache. [Code: 2]
* Note: Data above shows WinINET's current cache state, not the state at the time of the request.
* Note: Data above shows WinINET's Medium Integrity (non-Protected Mode) cache only.​

 

Could you please let me know why the below timings are shown as 0

 ServerBeginResponse: 00:00:00.000
GotResponseHeaders:  00:00:00.000

I suspect that the request is not sent to server but fiddler time logs shown ​connected to server with timings as below

ServerConnected:     15:14:32.007
FiddlerBeginRequest: 15:14:32.007
ServerGotRequest:    15:14:32.009
ServerBeginResponse: 00:00:00.000
GotResponseHeaders:  00:00:00.000
ServerDoneResponse:  15:14:32.431

Any has experienced this issue? what are causes for this and how to fix issue.

Help is greatly appreciated!!..

 Thanks

Hello,

The data below indicate that Fiddler connected to the server and sent the request without error.

The server held the connection open for 0.4 seconds, then closed the connection without returning any data at all (even HTTP headers).

It's possible that there's data in the server logs indicating why it didn't respond to this request.
