So though I have a large collection of URLs (from my logs), I need to "implode" URLs on a one-by-one basis.

Why? Is the space savings that significant?

If all you have is a handful of substitutions, you can probably hand-pick the strings:

http www. .com .org .net :// index .htm .jpg .gif google yahoo mail news ebay

    Yes, the savings is quite significant. From a hand-selected list of one user's habits, I was able to reduce some pages by more than 20%.

    The other thing is that this is not a collection of URLs from across the entire web. The URLs being crawled vary, but the proxy is part of a kind of "portal". So there are potentially thousands of URLs, but they come from a select list of sites. Thus the reason I am looking for the weighting of substrings.

    If one URL or one particular site (i.e. a particular substring) is crawled extremely frequently, then imploding that string might be much more bandwidth saving than simply imploding "http://" on all URLs.
