>When I post data to my com server the server is truncating the string at 49152. I read where iis have a limit of 49K. I can't figure out how to get around this or where to change this limit. I'm using wconnect addpostkey with nhttpostmode set to 3 to send the string. IIS and Foxisapi are on the server end. Everything I read so far talks about getting data not much about sending data. Am I missing something?

As I see you use POST method to transfer the data. I also suppose that you send BINARY data? If so - we have a fix to FoxISAPI.dll that allows transferring of large amounts of binary data. (We made it for form-based file uploading see RFC#1867 http://www.ietf.org/rfc/rfc1867.txt)
