Betreff: [EZPROXY-L] Blocking / Anonymizing Page icon requests?

So, most browsers that request these files [1] don't bother to include cookies in their 'side' requests for them.

That can play absolute havoc with EZproxy, especially with AutoLoginIP, as it will just 302 the first request for each file, grant a new session, 302 back to original request, and then produce a
200 for the file (if found).

While most browsers are rather good about caching the responses per hostname, services that use multiple hostnames for load balancing and/or CDNs will trigger the requests with each new hostname. Some browsers will also retry requests for the same hostname if previous requests don't return a 200 response.

For an active browsing session, that can result in hundreds of sessions being activated in a very short time. While those sessions are usually dropped quickly as "Login never completed," they still ratchet up the "Peak sessions active."

We really need a version of NeverProxy that will bypass filename patterns instead of just hostnames or a version of AnonymousURL that can be set globally and not overwritten by the scattered "AnonymousURL -*" entries in the config files.

We could always just add AnonymousURL directives for the files to every stanza (or separately group the stanzas that need their own AnonymousURL directives, so we could just apply these once at the start of all the other stanzas), but geez...

Have others noticed this issue or have thoughts on how best to 'fix' it?

HTH,
David
