ISAPI_rewrite limits

    Hi guys.

    I have a client who has a *really* big site and some really terrible URL's to go with 90% of it.

    I am working with the sites developers to try and make improvements in terms of the SEO, and was told something that I didn't actually realise about IIS.

    There is a limit to the number of URL's you can redirect (mod_rewrite style) using ISAPI_rewrite.

    I was told that rather than producing rules in RegEx to rewrite the URL's, that you essentially say "Redirect (x)url --> (y)url". I was also told that the config file these URL's are stored in can't be any larger that 2 megs.

    Is this true?

    Anyone have any experience of using ISAPI_rewrite on IIS?

    Any information would be appreciated - I've tried searching for isapi_rewrite limits, but couldn't find anything...

    I don't know about the 2 MB issue, but you can definitely do a redirect without regex. Here's an example for a permanent redirect via ISAPI Rewrite:

    RewriteRule /somepage.htm http://www.yoursite.com/somepage2.htm [I,O,RP,L]

    But that's it, I*do* wan't to use regex...

    If I can set rules rather than individually rewriting each URL it's going to make life a million times easier.

    Ah, I must have misread your original post. In any case, it's the same anyway. You just put the regex instead of a direct file.

    So it works exactly the same (essentially) as mod_rewrite on Apache?

    I don't know anything about the mod_rewrite in Apache...so, I cannot speak on it. Sorry. All I am qualified to speak on is the ISAPI Rewrite. :)

    We've had to do this... you have to install an IIS module from helicon ($30) and it works with a config file pretty much like you use htaccess - regex and all.

    don't know about file limit - I'm SURE you'll fit it into 2meg though ;)

    We also have the IIS module from Helicon installed. Very easy to work with and their support is pretty good as well.
