So, my question - my answer. First of all, my supposition about "...I suppose, that this difference is explanation of Status code: 500 Internal Server Error in response..." was WRONG!
For all people, who want to uderstand post_multipart I recomend to read RFC1341 (http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html) My problem was on another side: I post "wrong" example in this thread - in cfhttp I rote "... <cfhttpparam type = "formfield" name = "wizardMode" value = "â¦">... " But actualy value was "-1". In CFML Reference on p.290 I found that: "...All form field data must be encoded in this character encoding, and ColdFusion does not URLEncode the data..."!!!!! That's IT !!!!! I forgot about URLEncodedFormat function - and this was my actual problem!!! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:343802 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
