Hello,

I am looking to set a TimeOut for my REST calls from PB12.5.2. Below is my code:

 

loo_xmlhttp = CREATE oleobject

loo_xmlhttp.ConnectToNewObject("Msxml2.ServerXMLHTTP.6.0")

loo_xmlhttp.setTimeouts(100,100,100,100)


// invoke POST method for REST web service
loo_xmlhttp.open (astr_rs.in_method_type, is_url_send, false)

// building HTTP request headers
lblb_args = blob(astr_rs.in_arg_data)
ll_length = Len(lblb_args)
loo_xmlhttp.setRequestHeader("Content-Type", is_headers_content_type)
loo_xmlhttp.setRequestHeader("Content-Length", String( ll_length ))
loo_xmlhttp.setRequestHeader("Authorization", "Basic " + is_headers_authorization)
loo_xmlhttp.setRequestHeader("If-Modified-Since", string(today()))
loo_xmlhttp.setRequestHeader("Accept", 'text/xml')


// send request XML
loo_xmlhttp.send(astr_rs.in_arg_data)

// response from the service
ls_status_text = loo_xmlhttp.StatusText
ll_status_code = loo_xmlhttp.Status
ls_response_text = loo_xmlhttp.ResponseText

 

The highlighted line of code is where I am setting a really low timeout interval (200ms). 

But I do not see that working. The service is taking close to 10secs to return and the Send function waits for that time. 

How do I achieve it? My aim is to set a timeout and close connection and return control to the application. 

Thanks

Praveen
