Re: XALLOC in program LIBHTTP/HTTPAPIR4

["Kim Gibson" <kgibson@xxxxxxxxxxxxxxxxxx>]

Good morning Scott,

I will be installing the beta version into my test library later this
morning, and I won't be messing around with TERASPACE. Trust me, I
really appreciate the help I receive on your forum, and would never
encroach upon your personal time or space, nor would I tell you to "fix"
something. In my experience, it's usually my own error that's messing up
the process, and not HTTPAPI.

That said, before I install the beta version today I need to solve
another problem. I've had contact from the company of the web service
I'm calling, telling me that I'm making multiple requests for the same
item, and this is resulting my receiving a response that is incorrect.

Here's what's going on: 

I work for a life insurance company. I'm sending a request to a web
service that includes personal information on an applicant. The response
I expect to receive contains prescription information for that
applicant.

I've used HTTPAPI previously to call a similar subscriber-only web
service that returns medical information (you helped me extensively on
this--thank you!)

BOTH services are telling me that I'm making multiple (2) requests. 

My call to the prescription service is just a basic http_url_post_xml:

rc = http_url_post_xml(                               
     'https://ws.notreally.com/services/eoservice.asmx'   
           : %addr(SOAP)+2                             
           : %len(SOAP)                                
           : %paddr(StartOfElement)                    
           : %paddr(EndOfElement)                      
           : *NULL );                                  
                                  
                     
I took a look at the top of my http_api.txt debug file, and it looks
like this:

HTTPAPI Ver 1.23 released 2008-04-24
OS/400 Ver V6R1M0

New iconv() objects set, PostRem=819. PostLoc=0. ProtRem=819. ProtLoc=0

Is there a clue here?? 

I don't speak DNS, and am not sure what the "DNS resolver retry:2" is
telling me. But seeing a "retry:2" leads me to believe it might be part
of the problem....?

Curiouser and curiouser...

Kim

Yes...  the beta version is definitely newer:
http://www.scottklement.com/httpapi/beta

Please try the beta first.  If that doesn't help, then try the debug 
file.  (I don't know if the debug file will help, though.)

This was an experimental feature that I disabled because it didn't work 
well.

As I've already said in previous messages, enabling HTTPAPI's teraspace 
support will break compatibility with Expat.  It's not a question.  It 
will break, believe me.

And I don't know what else it'll break!

Please only enable this *if* you are willing to debug the code yourself 
and get it working yourself.  If you enable this code and then post a 
message saying "Scott, you have to fix Expat and HTTPAPI because I 
enabled teraspace and now it crashes with memory errors that I don't 
understand." then I will not be very sympathetic.  It's disabled for a 
reason.
