# 4.1.  Calculating Table Size
#
#    The size of the dynamic table is the sum of the size of its entries.
#
#    The size of an entry is the sum of its name's length in octets (as
#    defined in Section 5.2), its value's length in octets, and 32.
#
#    The size of an entry is calculated using the length of its name and
#    value without any Huffman encoding applied.

# Let's do some high-level arithmetics here:
#
# - overhead: 32 octets
# - field name: user-agent (10 octets)
# - field value: software with dissociative identity disorder (44 octets)
# - total: 86 octets
