RE: [SQU] Squid and Exchange Outlook Web Access (FIX)

Using squid-2.4-200011210000 under cygwin1.1.5 modified the http.c file,
enums.h file and url.c files as below.
Changes are marked with the comment /* Added this line to accomodate
Microsoft Exchange 2000 Outlook Web Access*/

The solution was sourced partially from the archive but i couldn't
understand all the references to RFC's (Sorry I don't understand much C)
so found the similiar entries that were talked about eg METHOD_BMOVE and
METHOD_BDELETE and it worked. so here is 8-)

Modified http.c
httpMaybeRemovePublic(StoreEntry * e, http_status status)
{
    int remove = 0;
    int forbidden = 0;
    StoreEntry *pe;
    if (!EBIT_TEST(e->flags, KEY_PRIVATE))
        return;
    switch (status) {
    case HTTP_OK:
    case HTTP_NON_AUTHORITATIVE_INFORMATION:
    case HTTP_MULTIPLE_CHOICES:
    case HTTP_MOVED_PERMANENTLY:
    case HTTP_MOVED_TEMPORARILY:
    case HTTP_GONE:
    case HTTP_NOT_FOUND:
        remove = 1;
        break;
    case HTTP_FORBIDDEN:
    case HTTP_METHOD_NOT_ALLOWED:
        forbidden = 1;
        break;
#if WORK_IN_PROGRESS
    case HTTP_UNAUTHORIZED:
        forbidden = 1;
        break;
#endif
    default:
#if QUESTIONABLE
        /*
         * Any 2xx response should eject previously cached entities...
         */
        if (status >= 200 && status < 300)
            remove = 1;
#endif
        break;
    }
    if (!remove && !forbidden)
        return;
    assert(e->mem_obj);
    if ((pe = storeGetPublic(e->mem_obj->url, e->mem_obj->method)) !=
NULL) {
        assert(e != pe);
        storeRelease(pe);
    }
    /*
     * Also remove any cached HEAD response in case the object has
     * changed.
     */
    if ((pe = storeGetPublic(e->mem_obj->url, METHOD_HEAD)) != NULL) {
        assert(e != pe);
        storeRelease(pe);
    }
    if (forbidden)
        return;
    switch (e->mem_obj->method) {
    case METHOD_PUT:
    case METHOD_DELETE:
    case METHOD_PROPPATCH:
    case METHOD_MKCOL:
    case METHOD_MOVE:
    case METHOD_BMOVE:
    case METHOD_BDELETE:
    case METHOD_SEARCH: /* Added this line to accomodate Microsoft
Exchange 2000 Outlook Web Access*/
        /*
         * Remove any cached GET object if it is beleived that the
         * object may have changed as a result of other methods
         */
        if ((pe = storeGetPublic(e->mem_obj->url, METHOD_GET)) != NULL)
{
            assert(e != pe);
            storeRelease(pe);
        }
        break;
    }
}

    
modified the url.c file to look like this:

const char *RequestMethodStr[] =
{
    "NONE",
    "GET",
    "POST",
    "PUT",
    "HEAD",
    "CONNECT",
    "TRACE",
    "PURGE",
    "OPTIONS",
    "DELETE",
    "PROPFIND",
    "PROPPATCH",
    "MKCOL",
    "COPY",
    "MOVE",
    "LOCK",
    "UNLOCK",
    "BMOVE",
    "BDELETE",
    "BPROPFIND",
    "%EXT00",
    "%EXT01",
    "%EXT02",
    "%EXT03",
    "%EXT04",
    "%EXT05",
    "%EXT06",
    "%EXT07",
    "%EXT08",
    "%EXT09",
    "%EXT10",
    "%EXT11",
    "%EXT12",
    "%EXT13",
    "%EXT14",
    "%EXT15",
    "%EXT16",
    "%EXT17",
    "%EXT18",
    "%EXT19",
    "SEARCH", /* Added this line to accomodate Microsoft Exchange 2000
Outlook Web Access*/
    "ERROR"
};

The "SEARCH" was the method added.

and then in enums.h changed
enum {
    METHOD_NONE, /* 000 */
    METHOD_GET, /* 001 */
    METHOD_POST, /* 010 */
    METHOD_PUT, /* 011 */
    METHOD_HEAD, /* 100 */
    METHOD_CONNECT, /* 101 */
    METHOD_TRACE, /* 110 */
    METHOD_PURGE, /* 111 */
    METHOD_OPTIONS,
    METHOD_DELETE, /* RFC2616 section 9.7 */
    METHOD_PROPFIND,
    METHOD_PROPPATCH,
    METHOD_MKCOL,
    METHOD_COPY,
    METHOD_MOVE,
    METHOD_LOCK,
    METHOD_UNLOCK,
    METHOD_BMOVE,
    METHOD_BDELETE,
    METHOD_BPROPFIND,
    METHOD_EXT00,
    METHOD_EXT01,
    METHOD_EXT02,
    METHOD_EXT03,
    METHOD_EXT04,
    METHOD_EXT05,
    METHOD_EXT06,
    METHOD_EXT07,
    METHOD_EXT08,
    METHOD_EXT09,
    METHOD_EXT10,
    METHOD_EXT11,
    METHOD_EXT12,
    METHOD_EXT13,
    METHOD_EXT14,
    METHOD_EXT15,
    METHOD_EXT16,
    METHOD_EXT17,
    METHOD_EXT18,
    METHOD_EXT19,
    METHOD_SEARCH, /* Added this line to accomodate Microsoft Exchange
2000 Outlook Web Access*/
    METHOD_ENUM_END
};
