Send HAR Files

Before you send your HAR file:

• Rename it.
  By default, HAR files use the page URL as the name of the file. Files with .com extensions look suspicious to spam and phishing filters. Give the HAR file a descriptive name that doesn't include the full URL.
• Zip or compress it.
  Uncompressed HAR files may be over file attachment limits.
