Question

User9952089 posted

Respected Community Members,

Is there a differece in calling the web service methods using / vs OP = ??

When i consume the weather public web service ., i can consume using URL.asmx/Methodname , but when i try to consume web service hosted on IIS , it require URL.asmx\OP= methodname.

Any idea?? i s there a settings in IIS to differentiate that or it just nature of web service hosting in IIS vs other web server??

 

Thanks,

Nick

Hi,

ASMX web services use SOAP. SOAP requests use only POST to invoke methods. You will need to generate a proxy client in your aspx page to invoke the web service.

But for the WCF Rest services, it can use GET verbs to invoke web services. So the uri can be URL.asmx\OP= methodname.

Please try to the following article:
