IE inconsistency when receiving Location header with a URL hash
Raw
ie-location-hash-inconsitency.py
#!/usr/bin/python
#
# Demonstrates IE inconsistency when receiving Location header with a URL hash
#
# It maintains the hash after a POSTing a normal form,
# and loses it after a multipart POST with a file field.
#
# Inconsistency tested on versions IE8, IE9.
#
# 'pip install flask' then run and connect with your browser to port 5000.
