Joe,
It's possible but let me explain why I wouldn't do it (in addition to simply not having the time).
The way the rewrite works on the phpBB end is to simply replace certain strings site-wide.
That particular mod introduces a different string for a particular file, and would need a new rule for that particular mod for just that one file. I do not know the mod and have no intention of changing that (I just don't have the time).
So the best I can offer is some general advice on how to do it, and if you want to test away you can probably figure it out.
The code in includes/page_header.php for the rewrite mod has arrays to replace strings.
The first dynamic one corresponds with the first static one.
e.g.
Code:"'(?<!/)viewforum.php\?f=([0-9]*)&topicdays=([0-9]*)&start=([0-9]*)'",
is rewritten to:
Code:"topic-\\1-\\2-\\3.html",
Note the "([0-9]*)", that means it's a numerical variable that is supposed to be passed on to the static URL, and the "\\1" is where the first variable will be inserted for example.
So what you'd need to do is make a rule that captures the variable that mod introduces and make a rule for a new static url. I do not know what kind of variable it is, and don't have time to test the many combinations of rules and test for the problems a new rule can cause so I can't do much except to tell you to try to mimmick the rules and test extensively.
On the .htaccess end you'll need to mimick the existing rules and make a reverse of the rule you make in page_header.php.
Many mods out there introduce new things and I can't keep up with them.
Heck I was looking at my own code just now and do not remember all the implications of the rules off the top of my head.
So my only recommendation is to test and test. If I have time for this kind of testing of this mod I would do better to dedicate it to fine tuning the existing rules to incorporate SIDs for logged in members, so that the mod can use static URLs for everyone.
Quote:BTW. The googlebot did a deep search on my site about 3 weeks ago. It indexed 271 pages. Then it did another one three days ago. It indexed 670 pages. Should I expect the number of indexed pages to increase with each deep search? FWIW my site has got 6672 topics.
I really can't say without spending a lot of time analyzing your site and keeping up to date on the server logs.
One big misconception is that this mod will make Google spider you, and that's not accurate it facilitates it but Google's spidering is based on other metrics as well.
Think of it like this parable.
phpBB without the session change in the mod is like a locked house. Some spiders can still get in through the windows but will sometimes not think it worth it.
So addressing their session ID aversion is like opening the doors. Making the URLs static is like throwing the doors open.
Thing is, this doesn't mean the spider will want to come inside.
The other changes in the mod are like removing all the clutter and putting it in the closet, so that when the spider does come in it will find the things in the house that it is interested in more easily and will have a better impression fo the house.
Some changes are also dedicated to making the spider think the house is wicked cool and to recommend the house with greater prominence (i.e. better position on the SERPs).
So I don't know what Google will do with your site, I do not know how much they fancy your house.
Many many things go into how deep the spider will go, ranging from backlinks, link flow, how deep in directory structure the forum is and much more...
So I have no idea, I know how much search engines will spider my sites because I keep track of many of these things (for example, Google will probably spend about 5 GB of bandwith spidering my site if they do another deep crawl).
If your house is looking increasingly attractive and your topics are increasing I bet they will spider it more deeply.
Thing is, this may not correlate to a single deep crawl you seem to be thinking of.
Google is moving away from deep crawls to a more rapid fresh crawl system for fresher results.
Google is on A2K all day every day and not once a month for e.g.
The crawling behavior varies widely, and it's unclear where in the transition (between crawling styles) Google is right now.
