Chrome developer tool - Remove unnecessary header in network tab - google-chrome-devtools

Can I have less header in network tab? (picture)

The Requests table displays the following columns by default:
Name The filename of, or an identifier for, the resource.
Status The HTTP status code.
Type The MIME type of the requested resource.
Initiator The following objects or processes can initiate requests:
Parser Chrome's HTML parser.
Redirect An HTTP redirect.
Script A JavaScript function.
Other Some other process or action, such as navigating to a page via a link or entering a URL in the address bar.
Size The combined size of the response headers plus the response body, as delivered by the server.
Time The total duration, from the start of the request to the receipt of the final byte in the response.
Waterfall A visual breakdown of each request's activity.
Add or remove columns
Right-click the header of the Requests table and select an option to hide or show it. Currently displayed options have checkmarks next to them.

fiddler modify response header

I'm working with an API that doesn't yet have CORS setup. So, instead of waiting until that's setup, I thought I could use fiddler to add the Access-Control-Allow-Origin header to the responses coming from the server. I haven't used fiddler for a while and can't figure out how to add headers to the response. Is this not supported in the free version of fiddler-everywhere?
It's not ideal, but I found a workaround. After the requests have gone off once, I right-click the ones I'm interested in and select "Add new rule". The rule will automatically do an exact match to the URL and sets the action of "Return manually crafted response" If I edit the rule, the header can be added in the raw text.

Copy as cURL(cmd) adds invalid characters to form data

I want to use Postman to test server side validation so I used the browser to submit (valid) data to the server and in the network tab of Chromes developer tools used "Copy as cURL". Then, in Postman, Import->Paste Raw Text -> Import.
If I look at the request body the data appears on x-www-form-urlencoded tab and every value has a '^' character appended to it. e.g. JobId: 75051^
When I post it the server validation picks it up as invalid data e.g.
The value "75051^" is not valid for JobId
Edit
If I use "Copy as C=cURL(bash)" instead, the ^ characters are removed but the server doesn't like the encoding used on dates and times. e.g. T
The value '11%2F19%2F2018+12%3A15+AM' is not valid for Work Start Time
What is going on here? Can I get "Copy as cURL" to pick up my data correctly, or is there a better way to pick up the request and get it into Postman?
I found a better way to pick up the request and get it into Postman:
Install the Postman Chrome App instead of the desktop
app.
Install the Postman Interceptor Extension.
Open Postman and click on the Interceptor icon in the toolbar to switch the
toggle to “on”.
Browse to your website: the requests appear in Postman's history.
Go to Interceptor missing from native apps #1667 and vote for it

Chrome DevTools - how to track network request when URL triggers Save dialog

When the URL entered into the Chrome address bar results in the Save As dialog being popped (Content Type is not recognised), the network request never appears in the network tab in dev tools.
Is there a way I can track this to see the response headers from within Chrome, ie. without resorting to external tools like tcpdump or fiddler?
Yes, it's possible to access the request/response data in a more raw form using the network internals interface provided in Chrome. Navigate to chrome://net-internals/ (can't make it a link)
Click on the 'Events' links to see the recent requests and active sockets. I recommend using the filter at the top to remove some of the noise.
Select the relevant entry corresponding to the source type URL_REQUEST.
On the right hand side, you will see a whole load of data, but the request headers will appear under the HTTP_TRANSACTION_SEND_REQUEST_HEADERS section, and the response headers will appear under the HTTP_TRANSACTION_READ_RESPONSE_HEADERS section.
The following is an example from a simple Node server I set up to return a response with the 'Content-Type': 'application/octet-stream'} header. This forces the browser to download.

HTTP response code for stale pagination

I have a web service that runs a SQL query, sorted by one of several columns, and returns a single requested page (as in skip M limit N). The UI in front of it follows a 'load more' pattern, accumulating all loaded pages of results in one view.
The problem is new and deleted records, which can happen at any time, causing the result of a 'load more' to be wrongly aligned, and depending on the sort being used, even obscuring new records that should be shown. In addition to an automatic refresh on a timer in the frontend, I'm going to add a timestamp field to the RESTful request and response format to allow the webapp to detect that the view should be completely reloaded on a 'load more' call.
My question is, what HTTP status code is a best fit for this signal? In reviewing the codes I don't see an exact fit. I thought of using 302 Found with a link to 'page 1', but I wonder if that might cause unwanted caching of the redirect. I also thought of 400 Bad Request, but there's nothing actually wrong with the request, it's just the data needs to be reloaded.
Pages are served from a POST /path call where the requested page is provided in a JSON body.
I'm not a complete purist, so anything that would make it work without caching or other side effects is acceptable, but I would like to adhere to REST principles as much as possible.

Responses to POST requests are not cacheable unless you explicitly mark them as such. So you can use any combination of status code, response headers and response entity to communicate the “please reload” message to the client.
You can use conditional requests. Include your client’s timestamp in the If-Unmodified-Since header. Respond with 412 Precondition Failed if client is stale. The client will have to know how to reload.
You can try 307 Temporary Redirect, but only if you encode pagination in /path, because upon receiving 307, (I’m assuming you’re doing AJAX here) XMLHttpRequest will transparently re-submit the same POST request to the new Location (at least this is what my Chromium does). Your actual page JSON will have to include metainformation on the range it covers, so that the client knows it has to replace the rows, not append them.

Is it possible to change/modify properties of a CR using OSLC_CM?

Is it possible to modify a property of a change request by using the OSLC-CM REST API of a change management system. The system that I'm trying to achieve that is Rational Change.
I can browse and query via the REST API, but to modify anything I need to resort to command line which is rather slow.
Is there a way?
BR,

To update resources using the OSLC-CM REST API you simply just can use HTTP PUT. In order to do this, you'll first need the URL of the Change Request.
The steps to achieve this (using any HTTP client) are:
acquire URL for Change Request (usually done by query, or stored reference, etc)
Perform an HTTP GET on that URL, specifying a format for use in editing. This is done using 'Accept' header, some typical values would be 'application/xml', 'application/json' or 'application/rdf+xml'.
Note, it is a good idea to set the header 'OSLC-Core-Verson: 2.0' as well to ensure you are working with the 2.0 formats.
Once you have fetched the resource, modify the property to the value you want.
Using HTTP PUT, send the modified resource in the content body to the same URL you fetched the resource from.
Additionally you will most likely need to pass along some additional headers to help the server detect any possible conflict.
You should get back a 200 (OK) or 204 (No content) response on success.
An optimization would be to do the same steps as above but only request the properties of interest and only send them by using the selective properties feature of OSLC.
So I've finally got it working with some help from googlegroups
To recap what I've done so that someone else might benefit too (I really have searched for it and the IBM documentation is as in most of the cases not helping):
So to modify PR/CR' implement_actual_effort attribute on the Rational Change server the following procedure was successful (using Firefox REST plugin):
1. In Headers set: Accept to application/xml, Content-Type to application/xml
Put the oslc address of the cr i URL in my case it was:
http://[IP:PORT]/change/oslc/db/[DB hex ID]/role/User/cr/[web_encoded_name_of_the_CR]?oslc_cm.properties=change:implement_actual_effort
(note in browser http://[IP:PORT]/change/oslc/db/[DB hex ID]/role/User/cr/[web_encoded_name_of_the_CR] will open change page of the CR/PR)
In REST client set Method to GET and press SEND
Click on the Response Body (RAW), copy xml Body
Change Method to PUT, change the value of the attribute (in the xml in Body window)
Press SEND
Attribute should have been changed right now, and the response should be similiar to what you've sent, with the attribute showing the change.
Note that to change an attribute (called property from oslc point of view) one has to provide ?oslc_cm.properties=[properties delimited with comma]
and in the request body xml the same properties have to be present, if I remember correctly if the property isn't mentioned in the xml it will be set to default
I hope this helps someone
