Hi all.
I want to put a favicon on my application which is
under "abc" context, so when i write
"http://localhost:8888/abc/"; it put my icon on the
left of the url if you use Firefox ( i think you know
what i mean).
I matched it with this code on my sitemap
<!-- favicon -->
<map:match pattern="favicon.ico">
<map:read mime-type="image/x-icon"
src="include/images/favicon32x32.ico"/>
</map:match>
but it doesn't work.
You may want to check http://en.wikipedia.org/wiki/Favicon for full info
on favicons... traditional usage and newer practice.
The basic thing to know here is that traditionally, favicons were
associated with web *servers*, not web pages, and were assumed to be at
http://hostname/favicon.ico, i.e. in the root folder (of URL space at
least).
Assuming your subsitemap is not mounted at the root folder... e.g. it's
probably mounted with a prefix such as "myapp"... your subsitemap
matcher for favicon.ico will only match
"http://hostname/myapp/favicon.ico";. But your browser asks for a favicon
at "http://hostname/favicon.ico";, which will not match the matcher in
your subsitemap.
I see that on the cocoon main
sitemap there is a matching like
'pattern="**favicon.ico"' so i think that it matches
all favicons on all requests anywhere it is and
returns the cocoon one ("resources/icons/cocoon.ico").
So i get some questions:
1. Why doesn't it match mine if it is processed first
than cocoon main matching ?
In the Cocoon top-level sitemap, which comes first: the **favicon.ico
matcher or the matcher that mounts your subsitemap?
The matcher that mounts your subsitemap may be
<map:match pattern="mount/*/**">
<map:mount check-reload="yes" src="mount/{1}/"
uri-prefix="mount/{1}"/>
</map:match>
or
<map:match pattern="*/**">
<map:mount check-reload="yes" src="{1}/" uri-prefix="{1}"/>
</map:match>
If the favicon matcher comes first, that's why any requests for favicons
end up using Cocoon's favicon instead of yours, even if the request is
for a non-root-folder favicon (e.g. "http://hostname/myapp/favicon.ico";).
2. Is the request/respones cycle of favicon from the
browser always done to
"http://localhost:8888/favicon.ico"; or
"http://localhost:8888/abc/favicon.ico"; ?
Traditionally the former. See above. But in most modern browsers, you
can add <link> elements in your html <head> to specify what URL you want
to use for the favicon.
See http://en.wikipedia.org/wiki/Favicon#Guidelines
If i point to "http://localhost:8888/abc/favicon.ico";
i get my icon
So you must have your subsitemap mounted before the "**favicon.ico"
matcher in the Cocoon top-level sitemap.
but if point any other url mapped i get
the page but not my icon (i get the cocoon one) ...
That's consistent with the above.
I'm really confused with this. I hope anyone can help.
Thx in advance.
Hope the above helps. If you have more questions, let us know.
