Problem wirh received XML file.

[SantiMoreno]

Hi Abapers.

I'm writting a program which gets from an URL a XML file which is updated daily. For such purpose, I'm using the function HTTP_GET, which is running properly (through a Proxy Server which recognizes by IP).

As said before, the function is running properly but I'm not receiving the proper file: sometimes, I get the one from the day before and, somehow, it starts to get the newer one. When I call this file, I'm not using any setting for dates or similar because the daily file is available in the same URL.

I've also tested the function from a SAP System which acceses the Internet without a proxy and it gets the proper file in every moment.

So, the question is: Can the Proxy server being caching the file obtained? If not, have you ever got a similar problem similar to the one I'm describing?

More info: I'm using the function HTTP_GET in systems ECC 5.0 and ECC 6.0 in both cases.

Thanks for your helping.

Thanks, Durairaj.

I will try to follow what you suggest to goal it.

Anyway, I've found the solution of the problem I've got: it was due to the proxy configuration which needed an exception rule to retrieve properly the file I try to download.

Would the class you suggest overpass this proxy config or should the rule be implemented as well?

Best Regards.

i use a similar program using cl_http_client class (instead of http_get), (communicating via proxy) and dont have the problems you are mentioning.

i would suggest you to give it a try with this class, as this offers much more flexibility, in setting request headers , form fields, etc

is the xml location is in intranet or extranet? if its intranet then you dont need proxy right? in that case, unless you had activated the proxy settings from sicf->client->proxy settings, you dont need to do anything with proxy.

however, if the xml is on a extranet (internet) location , you may have to authenticate yourself via the proxy server to reach it , in such a case, this is what you have to do

call method cl_http_client=>create
  exporting
    host          = 'www.webservicex.net'
    service       = '80'
    scheme        = '1'
    proxy_host    =  wf_proxy
    proxy_service =  wf_port
  importing
    client        = http_client.

http_client->propertytype_logon_popup = http_client->co_disabled.

wf_user = user .
wf_password = password .

call method http_client->authenticate
  exporting
    proxy_authentication = 'X'
    username             = wf_user
    password             = wf_password.
