Re: [squid-users] Squid 3.3 Reverse Proxy Mode - 502 Errors when uploading files larger than 6MB

After further analysis, the issue only happens when using SSL (HTTPS). The problem does not happen when using normal HTTP. Here is an output of the trace: POST /products/application/WorkQueue/BatchExcel.aspx HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Referer: https://mysite.com/products/application/WorkQueue/BatchExcel.aspx Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible;
