Thanks for your report.

I can't repeat this problem. We also have about 18 test cases that use this feature and they keep working.

Also, you can easily try "curl -F foo=bar localhost" to see that it does indeed send a Content-Type: header.

Can you please provide a full C source code to a small application that repeats this problem?

** [bugs:#1415] Missing Content-type in form file upload**
**Status:** pending-needsinfo
**Created:** Mon Aug 25, 2014 07:42 PM UTC by Martín Perazzo

Bug is present at least from 7.32.0 to present, cannot reproduce on 7.26.0

On version 7.32.0-7.37.1 Content-Type header is missing. Trying to force the header with curl_slist_append does not work.
On version 7.26.0  is properly set to multipart/form-data; boundary=----------------------------0cea4077810c\r\n

Sample code:

~~~~~~
                curl_easy_setopt(curl, CURLOPT_POST, 1L);
		basename=strrchr(file_to_upload,'/');
		if(basename)
			basename++;
		else
			basename=file_to_upload;
#if DEBUG
		printf("File to upload: %s\n",basename);
#endif
		curl_formadd(&formpost,
                        &lastptr,
                        CURLFORM_COPYNAME, "fileToUpload",
                        CURLFORM_STREAM, data,
                        CURLFORM_CONTENTSLENGTH, (curl_off_t)st.st_size,
                        CURLFORM_FILENAME, basename,
                        CURLFORM_CONTENTTYPE, "application/octet-stream", 
                        CURLFORM_END);
                        
                
		
		//chunk = curl_slist_append(chunk, "Content-Type: multipart/form-data");		
		
		//chunk = curl_slist_append(chunk, "Content-Type: application/octet-stream");
		chunk = curl_slist_append(chunk, "UForgeScan-Rev: 1.0");
		chunk = curl_slist_append(chunk, "Expect:");
	
		
		if(fpoutput){
			chunk = curl_slist_append(chunk, accept);
			curl_easy_setopt(curl, CURLOPT_WRITEDATA ,(void*) fpoutput);
		}else
			curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, curl_devnull); 
		curl_easy_setopt(curl, CURLOPT_HTTPHEADER,chunk);
		curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
