The base config

[z12]

Is the "base config" the framework?
Perhaps we should use two different names for clarity.
The phrase "base config" sounds like content filtering is happening.

So simplifying the real steps involved...
Step 1: Create a framework.
Step 2: Build a config.

Here's some filters I think would be useful in the framework:
(Not actual filter names)

Headers:
Parse url (out): handy for checking url to see if it's offsite and whatnot.
Capture Real User-Agent (out): Could be handy, if it's spoofed.
Capture Real Referer (out): Could be useful for various filters if the header gets modified.
Flag Offsite urls (out): Real Referer exist's but is not same domain as url.
---
Content-Type: Capture (strip?) charset (in): useful info when injecting scripts and setting default if missing.
Content-Type: Filter xhtml as text/html: By default proxo doesn't filter xhtml. Probably the easiest way to do this.
X-Filter: Don't Filter local.ptron (in): However, I do fix the mime-type for local.ptron scripts.

Web:
Strip leading white space: Why chew up the byte limit needed for "Start" filters on white space.
UTF page converters: Filters won't match on UTF-16 or UTF-32 pages, it's uncommon but why not handle it.
Content Sniffer: At a minimum, checks if page is html or not.
Check Start Html: Arrange head tags so code can be safely injected. Marks where to insert head code.
Inject Head Code: Inject default js, css. Filter specific js & css could be injected afterwards.
Mark End Html: Useful for identifying the real end of page.
Identify "InScript": Probably a two part filter, one at top and bottom of web filters.

Of course, most of these filters would be setting some variables.
