r2282 - lastmod_keepalive
Updated my language files, 22 Mar 2007 19:41:20 is the last date.
On advanced preferences, I keep seeing lastmod_keepalive, wondering if it’s a duplicate of Send “Last-Modified” header?

No, it’s separate, it is there to fix a bug. However, it is kind of complicated to explain, so I hadn’t created the lang string for it yet.
Source comment:
# some mod_deflate versions have a bug that breaks subsequent
# requests when keepalive is used. dropping the connection
# is the only reliable way to fix this.With this info in mind, does the following string explain it well enough:
Compensate for persistent connection mod_deflate bug?

Re: r2282 - lastmod_keepalive
here. It’s pretty obscure, I wasn’t able to find out if it’s limited to specific versions or whether there’s a fix. Searching for combinations of “mod_deflate”, “keep-alive”, “304” will turn up a few scattered reports.
Basically what happens is, when you send a 304 response, mod_deflate botches it and includes some binary stuff in the http content (even though no content has been sent). Any subsequent responses sent in the same connection pipeline will be corrupt.

Interesting, I wander if this is related to a bug I had with Apache/PHP a few weeks ago (not TXP related, I was debugging PunBB 1.3 on my hosting).
