Customizing mod_include -- Print "virtual" or "file" attribute in handle_include method
Apache Development Gurus:
I've worked with Apache for awhile now, but this is my first time tinkering
with
the source code for one of its modules. I'd like to alter mod_include to
print
out as a HTML comment all server side include references. My apologies if
this
is a trivial matter.
For instance, if an HTML page has an SSI:
Mod_include outputs the content of /foo/bar.html:
(Content from /foo/bar.html)
I'd like to tweak mod_include to also output the fragment path:
(Content from /foo/bar.html)
I've been able to successfully print out the include path *after* the filter
has
processed the SSI, but I'd like to add a comment before processing of the SSI.
Here's a snippet of the handle_include method from mod_include.c that I've
changed:
//..etc..
parsed_string = ap_ssi_parse_string(ctx, tag_val, NULL, 0,
SSI_EXPAND_DROP_NAME);
//New code
APR_BRIGADE_INSERT_TAIL(bb, apr_bucket_pool_create("", strlen("' -->"),
ctx->pool, f->c->bucket_alloc));
//End new code
//Original source code -- continues to process include
if (tag[0] == 'f') {
char *newpath;
apr_status_t rv;
/* be safe; only files in this directory or below allowed */
rv = apr_filepath_merge(&newpath, NULL, parsed_string,
APR_FILEPATH_SECUREROOTTEST |
APR_FILEPATH_NOTABSOLUTE, ctx->dpool);
if (rv != APR_SUCCESS) {
error_fmt = "unable to include file \"%s\" in parsed file %s";
}
else {
rr = ap_sub_req_lookup_file(newpath, r, f->next);
}
}
else {
rr = ap_sub_req_lookup_uri(parsed_string, r, f->next);
}
//etc...
The modifications above will print the fragment path after the SSI content:
(Content from /foo/bar.html)
What updates do I need to make to this code to force the fragment path to be
printed before the SSI content:
(Content from /foo/bar.html)
Any guidance on this matter would be greatly appreciated. Thanks,
Travis
