I got the source file and function as,

    cache_cf.c / strtokFile()

I am Having doubts on strtokFile() code as,

strtokFile
LOCAL_ARRAY(char, buf, 256);

/* fromFile */
   if (fgets(buf, 256, wordFile) == NULL) {
/* stop reading from file */

Will squid only parse 256 characters of filter rules in that file? what will happened when the pattern limit exceeds 256 length?

Is it need to raise this buffer range of 256 more when try to make filtering with DB based?

We are needing your another guide on selecting Database. Which will be good to use? We are now progress with MySQL.

Thanks for your inputs.
