Http 401 Unauthorised

[Iain Adams]

I currently have a web service set that returns data. When I use these
services through a browser, everything works fine and the resulting xml
is displayed. However sometimes when I connect to the scripts using a
php script I get the error message Http 401: Unauthorised. This usually
happens after a short time, when the webservices have not been used. I
am connecting to the webservices using Http Post and cURL.

Re: Http 401 Unauthorised

In Addition the actual error message is

A SoapException occurred: Message: The request failed with HTTP status
401: Unauthorized. Exception: System.Net.WebE xception: The request
failed with HTTP status 401: Unauthorized.

System.Web.Serv ices.Protocols. SoapHttpClientP rotocol.ReadRes ponse(SoapClien tMessage

in \\mycomputer\\w wwroot\crmwebse rvice\getmultip leentities.cs:l ine 48

the Code this error refers to is actually Visual C# but is pretty
normal.


I just cant work out why sometimes it works and sometimes not

Evidently the resource you're trying to access requires authorization.
The 401 is a normal message from the server requesting your userid and
password.

Browsers handle this automatically. If this is the first 401 this site
has sent while the browser has been running, it will pop up the
userid/password box on your screen. It remembers this information for
the specific site, and on the next 401 sends it automatically (if it is
rejected this time, the browser pops the userid/password box again).

I don't know how the remote site tracks this information. Some do it
with sessions, some by tracking the remote ip, etc. And most have a
timeout involved.

If you've already retrieved some information, chances are the
authorization has timed out and the system wants to reauthorize you.
Check out the curl option CURLOPT_USERPWD .
