A.11 Request Methods

Table A-13 lists the distribution of HTTP request methods. This data is skewed because, by default, Squid does not forward non-GET method requests up to parent caches. Also, the ICP and Cache Digest protocols work for GET methods only. It is likely that most of the non-GET methods are forwarded directly to origin servers by the lower layers .

Table  A-13. Distribution of Request Methods (IRCache and Anon-U Data)
Method IRCache % Anon-U %
GET 98.78 98.31
POST 0.881 1.634
HEAD 0.293 0.058
PROPFIND 0.041771 -
MOVE 0.002518 -
PROPPATCH 0.002076 -
CONNECT 0.001292 -
DELETE 0.000474 -
OPTIONS 0.000414 -
PUT 0.000095 0.000180
COPY 0.000015 -
MKCOL 0.000007 -
LOCK 0.000007 -
TRACE 0.000001 -

Note that the Anon-U data doesn't have any WEBDAV request methods. Most likely, these methods were not in use when the Anon-U data was generated (May 1999).
