[jira] Created: (TAPESTRY-664) Issue with Asset URLs and proxies
Issue with Asset URLs and proxies
---------------------------------
Key: TAPESTRY-664
URL: http://issues.apache.org/jira/browse/TAPESTRY-664
Project: Tapestry
Type: Bug
Versions: 4.0, 3.0.3, 3.0.2, 3.0.1
Reporter: Henri Dupre
This is an issue that I have been having with Tapestry 3 but I believe it will be the same with Tapestry 4.
We are constantly getting somne of these errors:
An exception has occurred.
You may continue by restarting the session.
org.apache.tapestry.ApplicationRuntimeException
Service asset requires exactly 2 service parameters.
Stack Trace:
* org.apache.tapestry.asset.AssetService.service(AssetService.java:136)
* org.apache.tapestry.engine.AbstractEngine.service(AbstractEngine.java:889)
...
The source cause is that the URL used is silly:
characterEncoding UTF-8
contentLength 0
method GET
protocol HTTP/1.0
queryString service=asset&sp=S%2Forg%2Fapache%2Ftapestry%2Fvalid%2FValidator.js&sp=S3dfc7ba91240b3bbd49fbb3ccccefe31
The & are not escaped. I found out that all these silly queries come from proxies!
The proxies seem to somehow parse the html page and generate queries for everything that starts with http.

[jira] Commented: (TAPESTRY-664) Issue with Asset URLs and proxies

-----------------------------------------------
Seriously, how is this Tapestry's issue? If your proxies are misconfigured then everything breaks ... not just the asset service.
At least it is better in 4.0 with friendly URLs.

Henri Dupre commented on TAPESTRY-664:
--------------------------------------
Could there be a way to customize the exception behavior, or have more precise exceptions (containing the source)?
So that at least by overriding the exception management (don't know how this has to be done in TP4) in the engine, it is possible to easily ignore this error. If there could be a field in the ApplicationRuntimeException containing the service (source of the exception) it would make easier to ignore this error.
The real issue in large production applications is that this behavior floods the error logs with useless errors.
