Client Cannot Negotiate Request and Returns an HTTP 413 Error
If client certificates are enabled on a Web server, Web site, or on
individual directories or files on the site, clients might see an HTTP
413 error when uploading large files.
If a client sends a long HTTP request, for example, a POST request, to
a Web server running IIS 6.0, the IIS worker process might receive
enough data to parse request headers, but not receive the entire
request entity body. When the IIS worker process detects that client
certificates are required to return data to the client, IIS attempts to
renegotiate the client connection. However, the client cannot
renegotiate the connection because it is waiting to send the remaining
request data to IIS.
If client renegotiation is requested, the request entity body must be
preloaded using SSL preload. SSL preload will use the value of the
UploadReadAheadSize metabase property, which is used for ISAPI
extensions. However, if UploadReadAheadSize is smaller than the content
length, an HTTP 413 error is returned, and the connection is closed to
prevent deadlock. (Deadlock occurs because a client is waiting to
complete sending a request entity, while the server is waiting for
renegotiation to complete, but renegotiation requires that the client
to be able to send data, which it cannot do).
The solution is to ensure that client is not blocked from sending the
entire entity body. To do so, change the value of UploadReadAheadSize
to a value larger than the content length.
The following example shows how to set the value for
UploadReadAheadSize to 200KB on the Web server.
cscript adsutil.vbs set w3svc/1/uploadreadaheadsize 200 **WARNING NOT
CORRECT**
For more information about UploadReadAheadSize, see
UploadReadAheadSize.
=EF=83=A7 ENDSNIP
I believe that the parameter is a byte value not a KB value as after
running the command, with any interaction with the /reports site, I
rec=E2=80=99d the error:
=E2=80=9CThe request failed with HTTP status 413: Request Entity Too Large=
=E2=80=9D
i=2Ee I couldn=E2=80=99t do anything
My suggestion is to do a =E2=80=9Cget=E2=80=9D 1st to determine what the =
original
value is
cscript adsutil.vbs get w3svc/1/uploadreadaheadsize
Assuming that it is indeed a byte value, I set it to 200,000 bytes per
the following
cscript adsutil.vbs set w3svc/1/uploadreadaheadsize 200000
I just uploaded my largest report file of 76KB with no problems
I=E2=80=99d like to know what caused this problem in the 1st place =E2=80=
=93 if
anybody has any ideas, I=E2=80=99d be interested.
Thanks,
