You should use wwHttp not wwIPStuff since wwIPStuff has none of the proxy stuff implemented in it...

Give that a try...

>>Hi Ronald,
>>
>>Posting to a new URL and POSTing in general should never go to cache either on the client or server as those sort of things are not cacheable. It only applies to GETs generally.
>>
>>However, you might want to look into proxy settings on wwHttp to make sure the Proxy isn't interfering with you.

>>>Hi Rick,

>>>We are using the below code to send a file up to a web server from a client and it works well for a number of client. However, we run into an issue with a few clients that have proxies. We actually upload 3 files to the same IP address but different web pages we find it sends the first file and then skips the rest of the files. Our web guy thinks it has something to do with the cache so now we send the ?nocache= TTOC(DATETIME()) in hopes it would no cache the links but, it still does.
