following keys:< / p >

is in the reference set. The < tt class = "docutils literal" > < span class = "pre" > size< / span > < / tt > includes the overhead (32
bytes). The < tt class = "docutils literal" > < span class = "pre" > index< / span > < / tt > corresponds to the index of header table.
The < tt class = "docutils literal" > < span class = "pre" > name< / span > < / tt > is the header field name and the < tt class = "docutils literal" > < span class = "pre" > value< / span > < / tt > is the
header field value. They may be displayed as < tt class = "docutils literal" > < span class = "pre" > **DEALLOCATED**< / span > < / tt > ,
which means that the memory for that string is freed and not

available. This will happen when the specifying smaller value in

< tt class = "docutils literal" > < span class = "pre" > max_deflate_size< / span > < / tt > buffer. Since the header table size is still
< tt class = "docutils literal" > < span class = "pre" > max_size< / span > < / tt > , the encoder has to keep track of entries ouside the
< tt class = "docutils literal" > < span class = "pre" > max_deflate_size< / span > < / tt > but inside the < tt class = "docutils literal" > < span class = "pre" > max_size< / span > < / tt > and make sure
