The policy string itself is still built by the existing code in lib/htmshell.c, which now also knows how to format it as a response header. Both carry the same nonce, since getNonce() is one per process, so a page may safely have the header and the meta tag. Most pages pick it up from addHttpHeaders() in cart.c, the existing hook for extra response headers, which every cart based CGI already passes through. Six places build their own http header block and so call it directly: the two "too many requests" pages, the captcha and its error page, the hubApi help redirect, and the hgSearch redirect to hgTracks. Inline scripts on three of those pages now carry the nonce, and the policy allows the Cloudflare script the bot check loads, so the option works when it is turned on. The Cloudflare entry is the only part of this that takes effect with the option off. diff --git src/hg/hgc/hgc.c src/hg/hgc/hgc.c index 9ac00223254..df91197dcbe 100644 --- src/hg/hgc/hgc.c +++ src/hg/hgc/hgc.c @@ -23294,31 +23294,31 @@ firstTime = FALSE; else htmlHorizontalLine(); smp = sampleLoad(row+hasBin); sscanf(smp->name,"footPrinter.%d.%d",&offset,&motifid); safef(filename, sizeof filename, "../zoo_blanchem/new_raw2_offset%d.fa.main.html?motifID=%d", offset, motifid); safef(tempTableName, sizeof tempTableName,"%s_%s", smp->chrom, pslTableName ); if (!hFindSplitTable(database, seqName, pslTableName, table, sizeof table, &hasBin)) errAbort("table %s not found", pslTableName); sqlSafef(query, sizeof query, "select * from %s where tName = '%s' and tEnd >= %d and tStart <= %d" , table, smp->chrom, smp->chromStart+smp->samplePosition[0], smp->chromStart+smp->samplePosition[smp->sampleCount-1] ); - printf("Content-Type: text/html\n\n \n", filename); } } void humMusClickHandler(struct trackDb *tdb, char *item, char *targetName, char *targetDb, char *targetTable, boolean printWindowFlag ) /* Put up sample track info. */ { char *words[16], *dupe = cloneString(tdb->type); int num; int wordCount;
