the response this:

post2015-04-01 11:58:13get on outfilename =/exnfs/uat2/requests/001152/11525750/dispatch/simulated_output_n150324_001_31_r_hcp_60.pdf.xml,   

i asked supplier if link "/exnfs/uat2/..." should using retreive xml file, in whihc case need prefix. should ignore link there validation purposes , there should xml file attached post.

according response, request method post, there no entries being given $_post in foreach loop , path being returned $_get , there no $_files.

can me interpret response please. possible there file there somewhere path being sent post/get(? not sure which?) , how retreive file if exists. thanks.
