* BUFSIZE defines the size of a read and write buffer. It is the maximum
|
|
* amount of bytes which can be stored by the proxy for each session. However,
|
|
* when reading HTTP headers, the proxy needs some spare space to add or rewrite
|
|
* headers if needed. The size of this spare is defined with MAXREWRITE. So it
|
|
* is not possible to process headers longer than BUFSIZE-MAXREWRITE bytes. By
|
|
* default, BUFSIZE=16384 bytes and MAXREWRITE=BUFSIZE/2, so the maximum length
|
|
* of headers accepted is 8192 bytes, which is in line with Apache's limits.
