Inject html into response body

[Oğuzhan TOPGÜL <og...@gmail.com>]

Hi,
I' ve search for all the archieve but i couln't find the answer, may be i
missed up, don't know.
I'm trying to write an apache module and i want to inject some html code
into resonses.
It might be in body, header or footer. The only thing that i want to
implemet is inserting an url or a text into all response bodies without
damaging the original page that is serving.
Is there any basic way of doing that?

thanks

Oguzhan

Have a look at mod_footer. However you're right, it's not as easy as
one might hope.

Be aware that output filters are harder to get RIGHT than they appear 
from the book and other similar sources. All of the other types of 
modules other than filters are farily straightforward to learn from 
the book or well known examples, in my opinion. The common examples 
for filters show how to cause yourself problems, though. Examples in 
the book consume memory proportional to the size of the resource, for 
example, thereby creating a denial of service that could be triggered
accidentally or on purpose. Other examples mess up range requests and 
other responses that aren't trivial. So I agree, it's "not that much
easy". It's easy to write bad filter, difficult to write a proper one.
(Too difficult for me, perhaps.)

No, there is no particular web site whoose HTML is tailored for this
purpose. At first i think this is not that much hard to add just a url or
just a text at the end of the page as a footer. But now, i think this is
not that much easy to apply.

What's your thinking on how you are going to parse the HTML to inject the
code?  Do you need to parse arbitrary HTML from any website or is this
filter targeted at a particular site whose HTML is tailored for this
purpose?

Well, why don't you just write an output filter that does this? I think
Nick's book will provide all the information you need.
Or have a look at mod_include in apache's source code.
