Thanks. I have to get a nightly build going on that, will fix.

There will be another pass through the bugdb on this as well, against the other proxy issues.

Release:

intended for 1.3/2.0 release date

httpd 1.3.x)

   Source for HTTP/1.1 mod_proxy is now available
    in httpd-proxy/module-1.0/ via CVS
   Note: this code now maintains binary compatibility

   CVS snapshots of HTTP/1.1 proxy + apache 1.3-current are at
    http://cvs.apache.org/builds/httpd-proxy/


Re intended merge of this code with 1.3.x, note that -Wall compilation produces
an error in proxy_cache.c, in the function ap_proxy_cache_conditional. The
problem is that wetag is used without initialization in the case etag is NULL.


The if statement

836:    else if (wetag && ap_proxy_liststr(c->inm, wetag, NULL)) {

should perhaps be changed to

836: else if (etag && wetag && ap_proxy_liststr(c->inm, wetag, NULL)) {

Another approach is to initialize wetag to NULL in its declaration

728:    const char *etag, *wetag = NULL;

Yet another approach is to set it to NULL if etag is NULL

730:    /* get etag */
731:    if ((etag = ap_table_get(c->hdrs, "Etag"))) {
732:        wetag = ap_pstrcat(r->pool, "W/", etag, NULL);
733:    } else wetag = NULL;

If nothing is done, the results are unexpected. I.e., this is not a matter of
mere cosmetics, but a real bug. I regret I didn't send this in before, but
since it seems apache 1.3.x with the new proxy will actually be used before
2.0.x is in production, I think it should be clean.


Sincerely,

Zvi.
