Perhaps one could use something based on the way squid currently does that task.
1. If the URL has a ? anywhere within it, squid assumes it to be a dynamic URL.
2. One of squid's configuration parameters specifies a collection of directory names which, if found in the URL with / on either side of them, and with at least one element after them, are taken as indicating that the URL in question is a DYNAMIC one.
3. Any URL not satisfying one of the above rules is taken to be a static one.
Rule 1 is simply a case of...
Q> if (index(url,'?') != NULL) Q> dynamic = TRUE;
...and rule 2 suggests the use of /proc/sys/khttpd as a file to specify the directory names to look for in rule 2, with the default contents being the same as the squid defaults.
Best wishes from Riley.
