Remote Server Return Error: (411) length required

One day, adjustedProgramWhen a problem occurs, the customer reports "remote server return error: (411) required length". The customer does not have a network, and this error has never been seen before ......

Cause: the httprequest POST method and get method are incorrectly used.

When the request is a POST method, the request content must exist. If no content is requested, the above error is reported.

Change to get.

Note: iis5.1 does not perform the above check (XP), and does not check the web support provided by vs2005. Iis6.0 performs the preceding check (win2003 ).
