Is O2 using a proxy and compressing images?

If I view sites or images in some apps using 3G the images are very compressed and full of artefact.
I assume they must be using some kind of proxy server that compresses images to reduce bandwidth.
Anyone else or just me?

My vodafone 3g usb dongle does the same.
I read a few threads about the place which suggest O2 users are stuck with it on what is effectively PAYG (even 30 day recurring), whereas contract users can alter settings to get proper images.
The heavy compression is not acceptable for use on the device like an iPad, so if O2 can't sort this out I may well change to 3 - good to hear you get good speeds with them and uncompressed images.
I think concerned UK O2 iPad users should vote with their feet if support queries can't help.
Compression might be fine for some people, all we need is the choice, after all we're paying for a given data usage, so if we use more it'd generate more revenue for O2.

Hi All,
Please provide some clarifications for the below points :
What is Sproxy?
2.     Why we are using Sproxy instead of Idocs
3.   When we are going Proxy ?
4.   What are the types of proxy ?
5.   How to Create to Proxy ?

Thank you.

Hi Bharat,
You seem to have a range of Questions. I will try and answer as many as possible.
What is Sproxy?
SPROXY is a transaction [T-Code] on the SAP ECC/CRM etc side where you can see the objects designed in SAP PI ESR and develop its corresponding ABAP code. SPROXY T-Code displays the Service Interface. You can read more about it in the following site:
**************** - XI - ABAP Proxy communication
2.     Why we are using Sproxy instead of Idocs
For Certain implementations Standard IDocs may not be available and it is quite tedious to create a Z- IDoC and therefore it is advantageous to use Proxy. You can read more about this doubt in the following links:
Choosing to use IDOC standard or ABAP Proxy?
IDOC vs Proxy
ABAP Proxy Vs IDOC
3. When we are going Proxy ?
When there are no Standard IDocs available. Please refer above links to get an answer for this.
4.   What are the types of proxy ?
5.   How to Create to Proxy ?
Again the following link has the answers for both these questions:
**************** - XI - ABAP Proxy communication
6.   What the Difference between SProxy and Idocs
Difference is in the way the communication happens. Standard Idocs are already provided and you can use them directly while Proxy you will require to write the code on ECC side. You can refer the following link to understand more:
Advantage of ABAP proxy over BAPI
7. What is SOAP file? When we are using SOAP file ?
I have not heard of anything called SOAP file. SOAP is a protocol used for communication and you can send files as attachment in your SOAP to Any(file/idoc/Soap etc) or vice Versa Interfaces. Infact Proxy itself is SOAP based communication with XI 3.0 Protocol.
Please explore SCN to know more about the various scenarios. There are endless possibilities in SAP PI.
Hope this Helps.
Thanks & Regards,

Difference between invoking a method using reflect.proxy and reflect.Method

Could any one tell me the difference between invoking a method using reflection java.lang.reflect.Method and java.lang.reflect.Proxy
using both the class, we can invoke a method at runtime
1)
Method mthd=cl.getMethod("methodName",parameterName);
Integer output=(Integer)mthd.invoke(new RunMthdRef(),input);
2)
Proxy.newProxyInstance(super.getClass().getClassLoader(), new Class[] { adapter }, new SomeClass(this));
Does anybody have any idea?

The two idioms are fundamentally different. Using java.lang.reflect.Method is how we call a method on a class, using Proxy is how we intercept that method call. An exercise for you, to illustrate that they do not do the same thing: write a simple class with one method, then use java.lang.reflect.Method to invoke that method, and then use a Proxy to invoke that method

I authenticate to the corporate proxy and then get the following detail about untrusted SSL connected:

Need some help using CSS Rules and Positioning Image Place Holders

Evening all,
I need to get this done by tomorrow so some speedy help would be very much appreicated!
I'm doing a website for an IT company, and as you may/may not know, support for XP and Office 2003 is dropped tomorrow - they want a button in the header of their site which basically says 'click here for upgrade advice' and when you click on it you're taken to a page telling you the benefits of upgrading. They want it to look like the mock up below:
I've had a right old job even getting the button (it's in PNG format) to go above the BrownTech logo. I inserted a placeholder, linked it to the PNG file, and then I made a custom CSS rule/class called '.header_fltrt' to put the image in and position it in that place, directly above the BrownTech logo.
To get the upgrade button in the desired position, here are the 'Box' CSS properties I used for the .header_fltrt CSS rule.
It's worth noting that the dimensions for the header itself are 960x235px, and the BrownTech logo is the background image for the header class (and is 960x235 in dimensions).
The problem I am having is that when I view the page in Design Mode in Dreamweaver, it looks fine, but when I view it in Live View or in a web browser, it looks like this:
As you can see, the upgrade button is not even visible!
Furthermore, when I go back into design mode on Dw, when I click on the upgrade button, I don't get any placeholder properties like I do when I click on green logo in the top left (which by the way is just a link back to the index page).
I'm not sure why this is but I cannot find any way to resolve it. I've even tried putting the BrownTech logo on a transparent background thinking that the block white background may be covering the upgrade button, but that's not the case.
Sorry if I haven't explained it very clearly. Hopefully you can see my problem.
Any help in etting the upgrade button to preview in the correct place would be very much appreciated!

Try this in place of what you have now.
.header {
    background-color: #FFFFFF;
    min-height: 335px; /**adjust as needed**/
    width: 960px;
    background: url(../assets/banner2.png) no-repeat;
.header_fltrt {
/**no floats or positioning required**/
    width: 552px;

Automatically logging onto Firefox using a Proxy and Network ID and Password

I am using Firefox on a University network, where I have been provided with a username and password. However, I am prompted to enter them every time I open Firefox.
How can I make it so that those details are stored in Firefox and it automatically logs me in every time I open Firefox, without having to change the Proxy settings? (currently set as "Automatically detect settings")

Yeah, I had done everything correctly. Turns out the problem was on the server end, though I didn't get an explanation exactly why applications run through OSX didn't work, including Safari, but 3rd party browsers did...

I am using Photoshop CS3 and the image looks ok on screen, but when I print the image is greenish.

I have checked with the printer's help desk and they say that this problem is not the printer, and there are no settings to change on the printer. Adobe no longer supports CS3. The immages look OK on screen, but when I print the page, the immage comes out kinda greenish, (more like, quite greenish). I don't know how to fix this problem or where to adjust any settings. Also to mention, the images are completed after a 2 day process, and this musst be done by Dec 22, 2011. Are there simple print options that will fix this problem?

You're getting into color management territory here and you need to target troubleshooting more specifically.
Basically you have a document profile that defines the colors. That profile is then converted (translated) into
1. A monitor profile for display, and
2. A printer/paper/ink profile for print.
If both profiles are good you'll get a reasonable match (allowing for the inherent differences between screen and paper).
If they don't match either could be wrong. So first off, is the monitor calibrated, or are you using the Windows default (sRGB), or a manufacturer provided profile?
Second, printer color management can be a bit obscure in that some manufacturers "hide" color management by doing it all under the hood and expecting sRGB input. Others, like Epson, allow you to pick the profile. This makes everything more transparent and makes troubleshooting much easier.
EDIT: cross post.

Using reverse proxy and terminating ssl on them

Hello
I am trying to set up IAS 9.03 on 2 machines one holding the infrastructure and one holding the midtier.
We want to terminate the ssl traffic on reverse proxys on apache. I am not very good at this so i am looking for a solution i read that you can do this in the whitepapers on the subject IAS.
Much thanks for any answer.
Boris

1) So initially we had the following:
<Object name="reverse-proxy-/">
Route fn="set-origin-server" server="http://server-backend"
</Object>
... and when getting a 401 from the back-end server it would seem that entering credentials in the dialog prompt does not work as is OOB; had it worked we would not have attempted anything further and hence this post would not exist... if we directly access the back-end server our credentials work so that is not the issue.
2) I agree that the "set-basic-auth" directive should be removed - as it is clearly to supply a user id and password - what was provided was a far fetched attempt to get this to work and will clearly remove it as well as the "forward-proxy-agent" and "forward-proxy-auth"
When you configure Web Server 7.0 as a reverse proxy, basic auth should work out of the box. If it doesn't, I recommend looking at the HTTP messages to figure out what's gone wrong. If you don't know how to do that and you have a support contract, Sun support should be able to help you.That is interesting - is this OOB feature documented anywhere?
I'll turn up the log level on the RP and see what happens - if I turn it high enough should I be able to see the request headers being forwarded; I'll also try to look at the backend server logs. Is there anything else you suggest - i.e. should be trying to snoop the traffic....

Apache Reverse Proxy and Branding Image

Hi,
I just installed a Apache reverse proxy on solaris. Unfortunatly, the branding image on the EP logon screen is not displayed. Anyone who knows how I can fix that?
I read some good post for the IIS reverse proxy. Is there a way to do the same on Apache?
Thanks
Elvez

Thanks for the replies.
However, I found the solutioin in an excellent document on the Web: http://www.apacheweek.com/features/reverseproxies. It would be worth reading for SAP. I'm especially referring to the document "Apache Configuration for J2EE Web Applications". The configuration described in the SAP document is strongly avoided by the author of apacheweek.

Gzip compression issues from using a proxy?

Hello I am unable to load some websites now from suspected gzip compression issues? I have been using a proxy and now my firefox browser is messed up Plz Help [email protected]
Thanks

It is possible to autenticate to a proxy server, but the question is what tye of authentication your proxy is carrying out . "Basic" or "digest".If it is Basic then you can use Base64 authentication scheme. You have to first set the System property variable to find proxy server (like port and IP Address)

Sites keep asking for username and password and say "restricted". I've tried numerous fixes and am not using a proxy.

Hi,
I wonder if someone could help me please.
I have an issue that extends across my browsers – Firefox and Internet Explorer (Firefox is default) and both are the latest version possible. My machine is fully patched (Win7 Pro x64 SP2).
The issue is as shown below:
'The site xxxx is requesting a user name and password. The site says: "restricted"’
The happens for some (not all) sites and I have to click “cancel” twice to remove the dialogue box, and then the site appears and works normally for a little while. The box will come up again if I attempt to click any links within the same site. It’s incredibly annoying and has been frustrating me for the past month. Here’s what I have tried so far, but hasn’t resolved the issue: 
 
• Clearing Firefox cache/history manually (set to never remember anything) 
• Tried checking/unchecking private browsing 
• Made sure “accept 3rd party cookies” is enabled 
• Tried all checkboxes for “no proxy”, “use system proxy” and “auto detect system proxy” etc 
• Disabled all add-ons/extensions within Firefox and retried 
• Performed the option to “Reset Firefox” to its default state from within “Troubleshooting” 
• Completely uninstalled and re-installed Firefox (latest version) 
• Went to the URL "about:config" and searched for the key "network.websocket.enabled" and switched it to "false". 
• Went to the URL "about:config" and searched for the key "network.proxy.share_proxy_settings" and switched it to "false". 
• Went to the URL "about:config" and searched for the key "network.automatic-ntlm-auth.allow-proxies" and switched it to "false". 
• Run a full AV scan in safe mode (with latest definition files) using Avira Antivirus, Spybot Search & Destroy, MalwareBytes, Super Antispyware and performed full optimisations via Registry Mechanic, Tune-up Utilities 2013 and CC Cleaner (with CC Extender installed). No threats found. 
None of the above has helped. The problem is only recent so I’m not entirely sure what’s changed.
Does anyone have any ideas or suggestions? I seem to have exhausted my ability to diagnose the fault via the god of Google 

Malachor

It is always best to avoid using such external cleaners as you can never be sure if they aren't corrupting files and it is usually not worth the trouble to repair damage if that is the case. A lot of the SQLite database files use a complicated table setup that can easily get corrupted.

Upload and Resize Image not inserting filename in database

I have a form that I created using the insert record form wizard. One of the fields is a file field and my form enctype is set to multipart/form-data. I then used the upload and resize image behavior and set the parameters. When testing the form the file uploads to the correct directory but no entry is made into the database for that particular field. The other fields are entered into the database just fine. If it helps, here is the code generated before the tag:
 
 <?php require_once('../../Connections/test.php'); ?>
 <?php // Load the common classes require_once('../../includes/common/KT_common.php'); // Load the tNG classes require_once('../../includes/tng/tNG.inc.php'); // Make a transaction dispatcher instance $tNGs = new tNG_dispatcher("../../"); // Make unified connection variable $conn_test = new KT_connection($test, $database_test); // Start trigger $formValidation = new tNG_FormValidation(); $tNGs->prepareValidation($formValidation); // End trigger //start Trigger_ImageUpload trigger //remove this line if you want to edit the code by hand function Trigger_ImageUpload(&$tNG) { $uploadObj = new tNG_ImageUpload($tNG); $uploadObj->setFormFieldName("picture"); $uploadObj->setDbFieldName("picture"); $uploadObj->setFolder("../images/"); $uploadObj->setResize("true", 120, 0); $uploadObj->setMaxSize(1500); $uploadObj->setAllowedExtensions("gif, jpg, jpe, jpeg, png, bmp"); $uploadObj->setRename("auto"); return $uploadObj->Execute(); } //end Trigger_ImageUpload trigger // Make an insert transaction instance $ins_team = new tNG_insert($conn_test); $tNGs->addTransaction($ins_team); // Register triggers $ins_team->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1"); $ins_team->registerTrigger("BEFORE", "Trigger_Default_FormValidation", 10, $formValidation); $ins_team->registerTrigger("END", "Trigger_Default_Redirect", 99, "../team.php"); $ins_team->registerTrigger("AFTER", "Trigger_ImageUpload", 97); // Add columns $ins_team->setTable("team"); $ins_team->addColumn("id", "NUMERIC_TYPE", "POST", "id"); $ins_team->addColumn("sort", "NUMERIC_TYPE", "POST", "sort"); $ins_team->addColumn("name", "STRING_TYPE", "POST", "name"); $ins_team->addColumn("title", "STRING_TYPE", "POST", "title"); $ins_team->addColumn("description", "STRING_TYPE", "POST", "description"); $ins_team->addColumn("picture", "FILE_TYPE", "FILES", "picture"); $ins_team->setPrimaryKey("id", "NUMERIC_TYPE"); // Execute all the registered transactions $tNGs->executeTransactions(); // Get the transaction recordset $rsteam = $tNGs->getRecordset("team"); $row_rsteam = mysql_fetch_assoc($rsteam); $totalRows_rsteam = mysql_num_rows($rsteam); ?>

If the reason is about memory, warning message should be happened when upload the image, because "show thumbnail" means resize at second time, how come you failed to resize the picture that system let it upload succeed at the first time by the same resize process?
upload procedure
a.jpg: 2722x1814, 1.2mb
upload condition: fixed width 330px, 1.5mb
"upload and resize" a.jpg -> file upload -> "resize engine" -> passed (but not work and no warning message)
"show thumbnail" a.jpg -> "resize engine" -> failed (not enough memory)
it doesn't make sense.
and you miss an important key point, I upload the same picture myself, and resize work, so I said it happened at random, and that's why I am so worried.

Abap proxy and java proxy

Hi
Could you plz tell me when should we select ABAP Proxy and when should java proxy ?? Is it like that in SAP systems we use ABAP proxy and non-sap systems we use JAVA proxy ??
Thanks
Kumar

To connect to SAP system with WAS >= 6.4, ABAP proxy is used.

Is it like that in SAP systems we use ABAP proxy and non-sap systems we use JAVA proxy ?? 
Not always. As i mentioned the limitation of ABAP proxy.
Also, Java Proxies cannot be used for any non-SAP application. it is generally used for communication with Java Application

When to use ABAP proxy?

currently we have MQ > XI > ECC 5.0(using RFC adapter which calls a BAPI)
the above scenario works sometimes, but other times the data is inconsistent. We are using BPM collection in XI and then transferring the order via RFC adapter.
I am wondering if we can use ABAP proxy and see if this method is more viable.
regards,
tony

Hi Tony,
>>>I am wondering if we can use ABAP proxy and see if this method is more viable.
Sure you can use proxies
if you are calling bapis and you don have sp14
then your server proxy will look very similar to
your RFC wrapper
